Introduction
As far as we know, there are nine planets locked in orbit around the Sun. Only one, our own Earth, supports life. But there are countless other suns
throughout countless galaxies scattered across the expanse of the universe. We still don't know if life exists on another planet in some othergalaxy.
Mercury
Named for the wing–footed messenger of the Roman gods, Mercury races around its orbit at a dizzying speed of 30 miles (48 kilometers) per second,
making the Mercurial year only 88 Earth days long. In contrast, one rotation around its axis–or a single day–takes almost 59 Earth days.

Greenhouse effect
Sunlight entering Venus's atmosphere is converted to heat radiation and is prevented from escaping by carbon dioxide–a phenomenon we call the
"greenhouse effect." Surface temperatures reach 800 degrees Fahrenheit (341.33 degrees Celsius), and the atmosphere appears to be constantly flashing
with lightning.
Weight of atmosphere
For an idea of the weight of Venus's atmosphere, consider that walking on the surface of Venus would be comparable to walking on the ocean floor at
a depth of half a mile.
Earth
For about 500 million years after its initial formation, the Earth remained at a rather stable 2000 degrees Fahrenheit (874.68 degrees Celsius).

Comprised predominantly of iron and silicates, the Earth also contained small amounts of radioactive elements, mostly uranium, thorium, and
potassium. As these elements decayed, they produced radiation that gradually heated the Earth, melting the iron and silicates. The iron sank to the
center, forcing the lighter silicates to the surface and causing the violent processes that formed the Earth's surface as we know it and that continue to
form it even today.
Geology
Between the iron core and the solid rock crust lies a mantle of heavy silicate rock that is 1800 miles thick (2880 kilometers). The mantle is neither
solid nor liquid, but has a viscous, yielding consistency upon which the crust actually floats. The crust is not a

Solar System: Chapter Analysis
The second chapter in increasing complexity explains the solar system, and our very own earth. My project is a painting of all the planets in our
solar system with the sun in the center of it all. In the days where there was no separation of religion, and state, it was thought that the earth was in the
middle of it all. This "truth" was then challenged by people like Ptolemy, and later confirmed using new science, and technology like Galileo's
telescope. Each planet orbits around the sun; in the order of Mercury, Venus,Earth, Mars, Jupiter, Saturn, Uranus, Neptune. This order took billions of
years to create, with each planet being formed by the most perfect circumstances.

Planet In The Solar System: Passage Analysis
The main point made in the reading passage is that the only one planet in the solar system with the possible to support life is the Earth. However, the
professor argues that titan moon also has potential for support life.
First, the reading says that Earth is the only body to have an atmosphere that contains the our life; hydrocarbons and nitrogen. On the other hand, the
speaker states in his lecture that moon also can find these things, which is important component for producing amino acids. This contradicts what the
passage indicates.
Second, the passage mentions that Earth's distance from the Sun, which possible to keep surface temperatures within a narrow range that ideal
environment. and can preserve liquid water However, the lecturer

The Solar System: The Milky Way
At the beginning of the solar system, in our universe, the Milky Way, the Moon (main character) is a planet and has a job to move in order with the
other planets as well as the Earth in the solar system in the Milky Way. The planets were in peace until the was formed. The Moon was lazy and did
not do its job as a planet, going anywhere and too close to the Earth, causing the oceans on Earth to cover the land by the rain in storms destroying
many buildings from towns and homes of many people and the people were drowning, depopulating the people on the lands worldwide. The Moon is a
planet in the Milky Way, as well as the Earth. Their jobs is to move in order with the other planets to avoid an incident or disaster to coexist that is called

Solar System Research Paper
Roughly 5 billion years ago, our solar system no sun. Instead all that exists in our solar system today, used to form a gigantic gas cloud, floating in the
milky way away from the center of the universe. Something traveling from the center of the universe faster than our gas cloud of a system collided
with our "solar system" this caused a fission reaction, creating a focal point that "sucked" in all the lightest of elements in our solar system, Mostly
Hydrogen I'd assume*. This is how our sun was created and like an implosion, the heat of this reaction, boiled the gasses, and the force of the object
that passed through our "cloud" created energy and momentum. The combination of heat, and movement, caused particles to collide, and bond together,

It was about 65 thousand years ago, that titans first set foot on planet earth. They immediatly sought out, and enslaved the new species of humanoids
that evolved from the minerals of Gaia and PanGaia combined. The slaves of the titans, were the people of Atlantis. The titans struggled to survive
on Earth, the intense gravity difference between earth and mars is the main reason that titans could not reproduce on earth. The failed reduction of
the Titans on earth created fear of extinction for the titans and caused great unrest on the planet mars. Mars was overpopulated and self destructive.
There was a point in time, when Mars had such a sever war, that the people of mars destroyed their own home planet, and suddenly within the course
of a few days, there was but a handful of their species remaining, both in space and on planet earth. It was the destruction of mars, that prompted
genetic diversity. The titans alive on earth, were in such fear of extinction *or just lonely?* that they began to splice their DNA with that of the people of

The Solar System Essay
Our solar system was born when, in a spiral arm of the Milky Way galaxy, a giant rotating cloud of dust and gasses began to collapse. Gravity
compressed the dust and gasses and the cloud got increasingly hotter and began to spin faster. During the following one hundred million years, the
gasses compressed until the center was so hot that nuclear fusion occurred giving off tremendous energy, combining charged atoms of hydrogen to
form helium. This process gave birth to a star, our Sun (Our Solar System, n.d.). Scientists have a good deal of data documenting the solar system's
history for about the last 3.9 billion years, but it was actually formed approximately 4.6 million years ago. The first 700 million years are somewhat of a

After the invention of the telescope, three more planets in the solar system were discovered: Uranus, Neptune, and Pluto. However, in 2006 Pluto's
classification was changed to dwarf planet (Our Solar System, n.d.). The eighth planet is, of course, Earth. In addition, there are 165 moons
gravitationally attached to the eight planets; three dwarf planets, Pluto, Eris, and Ceres, and their four moons; and billions of other small bodies (Solar
System, n.d.). Mercury, Venus, Earth, andMars are the inner planets and are called terrestrial (meaning earth from the Latin terra) planets because of
their similarities to Earth. The outer planets, Jupiter, Saturn, Uranus, and Neptune are Jovian planets and are so called because of their resemblance
to Jupiter. Jovian planets have gaseous outer layers. The planet closest to the Sun is Mercury and is a small planet with a rocky surface. Mercury's
diameter is 4,880 kilometers or 3,032 miles. Because its orbit around the Sun is oval shaped, its distance from the Sun ranges from 45.9 million
kilometers (28.5 million miles) to 69.7 million kilometers (43.3 million miles) and takes 88 days to complete its orbit. Mercury has no

Essay about Solar System
Solar System
Humans live on a small planet in a tiny part of a vast universe. This part of the universe is called the solar system, and is dominated by a single
brilliant star–the sun. The solar system is the earth's neighbourhood and the planets Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto
are the Earth's neighbours. They all have the same stars in the sky and orbit the same sun.
Scientists believe the solar system began about 5 billion years ago, perhaps when a nearby star exploded and caused a large cloud of dust and gas to
collapse in on itself. The hot, central part of the cloud became the sun, while some smaller pieces formed around it and became the planets. Other
fragments became asteroids and comets,...show more content...
Future manned expeditions could melt the ice into water, for drinking, washing and turning into rocket–fuel: there is enough ice to make a lake 10km
across and 10m deep.
Earth
If you approached the Solar System from space, one planet would stand out as very odd. The third world from the sun is brightly coloured, in shades
of mainly blue, with patches of red and green, and constantly shifting patterns of white cloud. And it has an unusually large moon; which–by contrast–
is dull and uniformly brown.
The perfect planet
Come closer, and you find blue is liquid water. This is the only rocky planet with water. Test the atmosphere, and again this planet is unique: the air
contains a lot of reactive gas oxygen. And finally, take a closer look at the green areas. Here there is ample vegetation and animal life. This is the only
planet in the solar system obviously inhabited life forms.
The earth is special mainly because it is located at the perfect distance from the sun. The temperature here is just right for water to exist as a liquid:
get in as close Venus and the water just boils away as steam, while as far out as the orbit of Mars water is frozen to ice.

Soon after the birth of earth, it was a very different place from the one we know today.
Its "air" was made of the unbreathable and

Solar System Formation Essay
Our sun is the central pivot point to which or entire planet and solar system is built around. With out it all life on our planet would cease to exist.
Within this paper we will explore how our Sun and solar system formed and came to resemble what we see today. The Big Bang, the alpha of
existence for the building blocks of stars, happened approximately fourteen billion years ago. The elements produced by the big bang consisted of
hydrogen and helium with trace amounts of lithium. Hydrogen and helium are the essential structure which build stars. Within these early stars,
heavier elements were slowly formed through a process known as nucleosynthesis. Nucleosythesis is the process of creating new atomic nuclei from

The smaller the nebula became the more dense and hot the center turned. Three distinct things happened as the nebula decreased in size: One, Due to
the properties of conservation of energy, as the cloud shrunk the gravitational potential energy of the particles within transformed into thermal energy;
two, due to conservation of angular momentum, as the radius of the nebula diminished the cloud would spin faster; three, the nebula transformed from
its original spherical shape into a flat, almost round, disk shape. This was due to the collisions of particles within the nebula as it collapsed. All three
of these are key points to how and why our solar system formed the way it did. The sun, the most crucial part of our system, was at the center of this
collapsing nebula. As stated above, as the gas cloud shrank the thermal energy increased, due to the conservation of energy. This increased the
temperature of the gas's within. The larger the center got the more thermal energy it would produce, hence heating up the cloud further, and the more
gravitational force it would impose on surrounding particles, resulting in the center becoming more massive. A protostar would eventually be born
from this process. The protostar would continue to grow, in size and heat, until reaching a temperature upwards of seven million degrees Celsius. At
this temperature a star is born, hydrogen is now able to fuse into

Planets and Solar System
"A planet is a celestial body that revolves around a central star and does not shine by its own light " (Grolier, 1992). The only planetary system that is
known to man is our solar system. It is made up of nine planets which range in size and make–up. The nine major planets in our solar system are
Mercury, Venus, Earth, Mars, Jupiter,Saturn, Uranus, Neptune and Pluto. There are also many other minor planets which are also in our solar system,
but they are unimportant compared to the nine major planets. In this paper I will discuss the planets and how they are each unique.

It is called this because it closely resembles the Earth's mass, density and diameter. The only thing different is that Venus " is shrouded in thick clouds
that completely hide the surface of the planet " (Grolier, 1992). The surface temperature is also much warmer than that of Earth.
Venus completes one revolution around the sun in 224.7 days.
This makes the Venusian day equal to 117 earth days. It is thought that this slowrotation may be the reason why Venus has no magnetic field.
The atmosphere of Venus made up of 98% carbon dioxide and 2% Nitrogen. This atmosphere also has the presence of helium, neon and argon. This is
yet another thing which makes Venus different from Earth.
The surface of Venus is quite a bit like that of the Earth.
The surface has volcanoes and smooth plains. " Much of the volcanic activity on Venus takes the form of Basaltic eruptions that inundate large ares,
much as the mare volcanism flooded the impacted basins on the near side of the moon " (Morrison, 93,
1993). One thing that differs from Earth is that there is no water liquid on the Venusian surface.
Some of the scientific data that follows was taken out of Cattermole's book. The mean distance from the sun is 108.20 Km.

The equatorial diameter is 12,012 Km and the equatorial rotation is 243 days. Finally the mass of Venus is 4.87*10^24 (Cattermole, 63, 1993). Venus,
although different than Earth, is still our sister planet.

First generation stars were massive and very hot. They did not contain heavy elements therefore they die faster than population II stars. Only
population I stars would have formed in stellar nebulas that contained dust of dying population stars III, II and the population I stars. These population
I stars have the coolest, smallest and the most lived stars. They were the only stars to have thought to be capable of having a solar system. Our solar
system and the sun came from population I stars.
The basic structure of our solar system consist of the Sun is in it center with many rocky planets in the inner parts which are Mercury, Venus, Earth

Essay On New Solar System
In this article, it states that 39 light–years away from Earth, there is a belief that science has found a new solar system. That very solar system is
special since it has seven planets that are very alike to our Earth. With the terrain being rocky and warm enough that it could support life on it. This
discovery is the first time people have ever found that out that there are rocky planets that are orbiting a single star. Before we have the technology we
have today, the only terrestrial planets we knew of being four planets. And we didn't even know much about oursolar system, other than our planet and
some a few others, but as we reach a new age in our world so many other windows are opening to us as a society.

Also in paragraph three, it states that "Last May, the scientists published that they had discovered three rocky bodies orbiting the star. They named them
TRAPPIST–в‚Ѓb, –в‚Ѓc and –в‚Ѓd. Later, Gilion realized that the dip in brightness he thought came from в‚Ѓd was actually caused by three planets all
crossing at the same time." They eventually realized that there were actually seven planets. The quote explains that all former three planets were
orbiting their own star, which were caused in a dip of brightness that caused the planets to cross at the same time. All TRAPPIST planets orbit the
same star, the line on which they orbit all move at the same times. They reach each starting point at the same time which is not really like other
planets we have ever heard of before, mainly because the all of the planets in our solar system all move at their own speed.
Including information comes from 'Planets Are Close Enough For Atmospheric Studies." Information for this comes from paragraph one, it states that
"For years, scientists have found evidence that our galaxy, the Milky Way, is full of Earth–like planets. However, the TRAPPIST–в‚Ѓ researchers say

It is the size of earth. The second planet is a little bigger than the first planet but it still can have civilization on it. This planet's name is Derigon. In the

The Solar System
Our complex of stars, planets, and all other celestial structures collaborate to run the quintessential system that we live in, which has been our home for
millions of years, the solar system. Yet, we commonly ignore the thought, why does our solar system, hence the word system, join effort with all
structures to create the exemplary world we know today? To figure out the answer to this question, it is essential to understand and appreciate oursolar
system. The world is exactly how we humans desire, convenient for us to simply state that the Earth is close enough to the sun that we receive ample
heat, yet not too far that we do not freeze. The solar system is a working system of countless stars, several planets and moons, and an abundance of
comets and space phenomena.
The study of our solar system is a major portion of the oldest physical science, which is referred to as astronomy. Space was quite well–known before
the inventions of major astronomical tools, as the six closest planets to the sun were already discovered (Mercury, Venus, Earth, Mars, Jupiter, and
Saturn). In addition, the motion of planets, moons, and other celestial structures were identified in order to produce calendars and navigation tools.
Astrology played a significant role in the lives of ancient civilizations, with stellar patterns and lunar cycles providing religious guidelines. Although
several ancient civilizations played a huge role in making groundbreaking discoveries, the Greeks took the

The Importance Of The Solar System
Solar System: The Sun and bodies orbiting it. The orbits of the Solar System appear stable considering there has been little change in the orbits
since the beginning of the Solar System. The Solar System lies in the disc of the Galaxy and moves around the galactic center about once every 2 x
10^8 years on a circular orbit with a radius close to 3 x 10^4 light years, about 2 x 10^7 miles. There are nine planets in the Solar System, Mercury,
Venus, Earth, Mars,Jupiter, Saturn, Uranus, Neptune and Pluto, Pluto is not a planet, but a dwarf planet. The Planetary System consist of
combinations o f gas, ice, and rocky giants; similar to Jupiter, Neptune, and Earth. Similar things to them are known to exist around many other stars.
The outer planets are Jupiter, Saturn, Uranus, and Neptune. Jupiter is 5.2 astronomical units (AU) from the Sun. Jupiter is by far the biggest planet
with a mass 318 time greater than that of Earth's mass, while the other giant planets are rock and bigger than Earth by a factor of 15 or more. The
outer planets are subdivided into gas giants or Jovian Planets, and ice giants. Jupiter and Saturn are composed of Hydrogen and helium gas much like
the Sun, but with ice, such as frozen water, methane, and ammonium concentrated in their cores. Uranus and Neptune also have rock and ice cores
surrounded by smaller amounts of hydrogen and helium. The word "planet" derives from the Greek word planasthai, meaning "to wander," and it was
used by ancient

Most bodies in the solar system that display a solid surface will show evidence of craters. Many craters are apparent on bodies with no atmosphere
such as Mercury or our Moon. Erosion and weathering have removed most of the evidence of craters here on Earth. Most asteroids follow simple
circular orbits between Mars and Jupiter and are occasionally agitated by each other or more regularly by Jupiter, however, comets can often come too
close to the Earth and other major bodies due to their highly elongated orbits (California Institute of Technology). Over time, every planet ormoon has
found itself in the wrong place in its orbit at the wrong time and has suffered a major impact. Multitudes of small debris the size of pebbles or grains
of sand beat the Earth every day but we are protected by the Earth's atmosphere. Several times a month small asteroids are spotted passing between
Earth and the Moon's orbit. Very small fragments of asteroids and comets called meteoroids hit the Earth's atmosphere and explode practically every
day causing the bright meteor events we see at night. Over the next 100...show more content...
It has been determined that we currently have over 100 ring–like structures on our planet that are meteorite impact sites. However, in the last 1,000
years, there are no known human deaths from the impact of a meteorite (Szoldra). Avoiding impacts requires the ability to better calculate statistics. To
do this, astronomers need to identify as many of the near–Earth objects as possible. Most astronomers believe that the systematic approach will give us
the greatest opportunity to identify the near–Earth objects that are big enough to actually cause catastrophic changes the environment of our

The Solar System
The solar system consists of our sun and everything that travels around it such as, eight planets and their moons, asteroids, comets, and other space
objects. Our solar system is constantly in motion and has an elliptical shape which means it looks like an egg. It is believed to be more than 4 million
years old and contain some of our most amazing discoveries. Theories suggest that our solar system along with our Universe formed due to the "big
bang." The big bang was an explosion that in response, Geologists believe formed the Universe and occurred about 13.7 billion years ago. In just a
matter of time, space and the building blocks of matter were created, and time soon began. From that moment, the Universe started to expand, and
continues to expand to this day. Over billions of years, matter formed into large, complex structures that continue to evolve. However, recent
speculations support the idea that the sun and planets concentrated from a nebula, which is described as a cloud of gas and dust in outer space. Particles
of dust accumulated together and formed small chunks and then expanded into larger ones eventually forming into planets. One of the most important
objects that was formed during this process was the sun.
Primitive astronomers once believed that the Earth was the center of the universe and that the sun and everything else revolved around it. Copernicus
proved that theory wrong and explained that Earth and the other planets in our solar system actually

What are planets? Planets are kinda like asteroid around the sun. There are nine planets in the solar system, Mercury, Venus, Earth ( Our planet ), Mars,
Jupiter, Saturn,Uranus, Neptune, and Pluto.
The Terrestrial Planets
The terrestrial planets are the four innermost planets in the solar system, Mercury, Venus, Earth and Mars. They are called terrestrial because they have
a compact, rocky surface like the Earth's. The planets, Venus, Earth, and Mars have significant atmospheres while Mercury has almost none. The
following diagram shows the approximate distance of the terrestrial planets to the Sun.

Prominences are immense clouds of glowing gas that erupt from the upper chromosphere. The outer region of the corona stretches far into space and
consists of particles traveling slowly away from the Sun. The corona can only be seen during total solar eclipses.
The Sun appears to have been active for 4.6 billion years and has enough fuel to go on for another five billion years or so. At the end of its life, the
Sun will start to fuse helium into heavier elements and begin to swell up, ultimately growing so large that it will swallow the Earth. After a billion
years as a red giant, it will suddenly collapse into a white dwarf –– the final end product of a star like ours. It may take a trillion years to cool off
completely.
Mercury
It is the closest planet to the Sun, and second smallest planet in the solar system. Its diameter is 40% smaller than Earth and 40% larger than the Moon.
It is even smaller thanJupiter's moon Ganymede and Saturn's moon Titan Mercury is one of the planet that doesn't have a moon or salitlite obriting

around it. Mercury obrit around ( and all the way ) the sun takes about 88 Earth days. Mercury has no atmosphere, and the planet is too small to hold
one. With no atmosphere, there is no heat, so it's temp. is about –133 C.Mercury was named by the Romans after the fleet–footed messenger of the
gods because it seemed to move more quickly than any other planet,obriting around ( and all the way ) the sun takes
