The Solar System and Beyond discusses the Sun, Mercury, and other planets. The Sun is over 4.5 billion years old and has burned through half its hydrogen, giving it another 5 billion years before swelling up and consuming Earth. Mercury orbits the Sun in an elliptical pattern between 47-70 million km away, completing an orbit every 88 days faster than any other planet at nearly 50 km/s.

An Exploration of the Comet
Comets are microscopic bodies made of ice and dust that formed during the early formation of the solar system. Their nuclei contain water, methane, and other ices. When heated by the Sun, these ices melt and form two tails - a dust tail and an ion tail. Comets originate from the Oort cloud and Kuiper belt, and are believed to have brought water and organic molecules to Earth. Famous comets include Halley's Comet which returns every 75 years, as well as Hale-Bopp and Hyakutake.
Space
The document provides information about our solar system, including details about the Milky Way galaxy, the Sun, planets Mercury through Neptune, Pluto, and the Moon. It notes key facts about each celestial body such as their age, position from the Sun, size, and other distinguishing features. For example, it states that Earth is the only planet known to have life and running water, and is the third planet from the Sun.
Space Debris
This document presents a seminar on space debris given by Lokesh Parihar to Anurag Garg. It begins with an introduction defining space debris and its history. It then discusses the different types of orbits where debris can be found, such as low Earth orbit and geostationary orbit. The document outlines methods used to track and measure debris including radar, radio waves, and space telescopes. Potential methods to clear space debris are presented, including electrodynamic tethers, laser brooms, solar sails, space nets, and collector satellites. The conclusion emphasizes the importance of addressing the growing problem of space debris to enable continued development of space communication and exploration.
Satellites
Satellites have evolved significantly since Sputnik was launched in 1957. Early satellites were simple devices that gathered basic data and demonstrated orbital technology, while modern satellites can cost over $1 billion and provide advanced capabilities like global communications, weather monitoring, and GPS. However, the growth of space debris is a emerging environmental issue as defunct satellites and fragments threaten future space exploration due to collisions.
life on mars
The document discusses the possibility of life on Mars and the exploration efforts to search for evidence. It notes that Mars' climate and surface age make it similar to early Earth and thus it may hold clues about the development of life. NASA missions have been searching for ancient life by looking for water and types of microorganisms. Understanding Mars could provide insights into Earth's history. There is also significant human curiosity to explore the red planet and search for answers to questions about its formation and the potential for life.
The Amazing Universe
The document discusses the amazing universe. It defines the universe as a space filled with matter and dark energy that is causing expansion. The universe likely began with the Big Bang around 13.8 billion years ago. It contains stars, planets, black holes, nebulae, asteroids belts, and moons. The universe remains mysterious but houses everything needed to support life.
Solar+system+presentation +team+c
The document discusses the formation of the solar system and properties of terrestrial planets. It provides information about asteroids, comets, satellites, and the minor planet Shakespeare. It also includes details about the exoplanet Kepler-22b and compares its properties to Earth and asteroids. Key facts about Kepler-22b are that it was discovered in 2009, has a radius 2.4 times Earth, and is the closest resemblance to Earth found so far, though its composition remains unknown.
Glaxies and the universe
Galaxies are large groups of stars, gas and dust bound by gravity. There are three main types of galaxies: spiral, elliptical, and irregular. Spiral galaxies have winding spiral arms, some with central bars. Elliptical galaxies are large and three-dimensional spheres. Irregular galaxies are smaller and less common with various shapes. Our Milky Way galaxy is a spiral galaxy containing one trillion stars, including our Sun. The Universe contains billions of galaxies, each with billions of stars, that is always evolving as new stars are born and old stars die.

G2 General Geography
1) The document provides an overview of the solar system, including descriptions of Earth, the Sun, planets like Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune, and other objects like asteroids and comets.
2) Key details are provided about each planet's composition, size relative to Earth, orbital properties, and number of moons.
3) The solar system consists of the Sun and 8 major planets that orbit it, along with asteroids in the asteroid belt between Mars and Jupiter and comets with elongated elliptical orbits.
Stars Inquiry
The document summarizes an experience looking at the stars on a porch, which led to questions about stars. It then provides information to answer those questions. The sun is the closest star to Earth at about 92 million miles. Stars form from clouds of dust and gas that collapse under gravity. Gravity helps hold stars in place through its pushing and pulling effects. To locate stars like Polaris, one must first look north and use knowledge of constellations.
Space Waste Management
The document discusses space junk, which refers to debris left in Earth's orbit from space missions and satellite launches. There are estimated to be over 10 million pieces of space junk currently orbiting Earth, posing risks to active satellites and space stations. Collisions between space junk have increased the amount of debris and make future space missions more dangerous. Researchers are working on methods like laser removal to reduce space junk and mitigate the growing problem.
Group 11 extra terrestrial-beings-and future exploration
The document discusses several topics related to space exploration and the search for life beyond Earth. It describes NASA's Viking missions to Mars in 1976 which included orbiters and landers that searched for evidence of life on Mars. It also discusses the concepts of planetary habitability and the potential for life to exist on other planets or be transferred between bodies. Private space ventures are working on projects like commercial space stations and orbital hotels to expand human presence in space.
Exoplanets definitivo (1)
An exoplanet is a planet that orbits a star other than the Sun. More than 1800 exoplanets have been discovered so far, mostly within the Milky Way. The habitability of exoplanets depends on factors like their location within the habitable zone of liquid water, and having an atmosphere that supports life. Exoplanets can be discovered through direct detection as they pass in front of their star, or indirectly by the gravitational effects on the star. Studying exoplanets helps understand the diversity of planets and could reveal if life exists elsewhere.
Baltazar,antonio, álvaro (new) mars
This document provides information about Mars, including:
- Mars was once warmer and wetter, with rivers and oceans, but its atmosphere depleted over time.
- Humans would weigh less on Mars due to its lower gravity.
- Robotic missions have explored Mars' surface and found evidence it could have once supported life.
- Mars has volcanoes, canyons, dust storms, and two small moons named Deimos and Phobos.
Space pollution.
The document discusses space debris and inactive satellites orbiting Earth. Thousands of fragments from old spacecraft and satellites travel around Earth at speeds over 20,000 km/h and can damage active satellites like the International Space Station. While there are many active satellites today, there are also a growing number of inactive, defunct satellites that remain in orbit and could collide with other objects. In total, there are more inactive satellites and fragments surrounding Earth than active ones currently in space.
07 lecture outline
The document provides an overview of the solar system and spacecraft exploration. It describes the key features of the solar system, including that the large bodies orbit in the same direction and plane, there are two main types of planets, and there are swarms of smaller bodies like asteroids and comets. It also discusses how robotic spacecraft can operate via flybys, orbiting other worlds, landing on surfaces, and returning samples. The goal is to understand patterns in the solar system that provide clues to how it formed and how spacecraft reveal information about other planets and moons.

Life on other planets
1) The document discusses the possibility of life existing elsewhere in the universe, beyond Earth. It explores potential habitats on planets and moons in our solar system as well as exoplanets orbiting other stars.
2) Estimates suggest there could be tens of thousands of civilizations in our galaxy alone, and planets like Mars may have supported life in the past or could still harbor microbes.
3) Moons such as Europa and Enceladus seem to have oceans below their icy surfaces that could support microbial life, while Titan has lakes of liquid methane on its surface. Over 400 exoplanets have been discovered so far in distant solar systems.
Comets and asteroids
This document provides information about comets and asteroids. It defines a comet as a small solar system body that displays a coma and sometimes tail when close to the sun due to solar radiation. Comet nuclei range from hundreds of meters to tens of kilometers and are made of ice, dust, and small rocks. The document discusses how Edmond Halley correctly hypothesized that the comets of 1456, 1532, 1607 and 1682 were the same object, now known as Halley's Comet, and how it returns every 75-76 years. It also mentions that the impact of a 10km asteroid may have caused the extinction of dinosaurs 65 million years ago based on geological evidence.
Webquest
This document contains a science web quest with information about the planets in our solar system as well as other celestial bodies. It provides details about each planet's composition, unique features, moons, and more. For example, it notes that Mercury has no atmosphere and Venus spins clockwise unlike other planets. Earth's atmosphere contains nitrogen, oxygen and trace gases. Mars may have ancient bacteria. Jupiter spins very fast and has a giant storm. Saturn has a low density and seasons lasting over 7 years.
Origin of star planets and life
The document discusses the criteria for defining planets in our solar system and beyond. It explores size, shape, orbit characteristics, historical classifications, and membership in populations like the Kuiper Belt. While size and orbit were traditionally the main criteria, the discovery of objects like Ceres, Pluto, and exoplanets require considering other factors. The International Astronomical Union is working to develop a definition that accounts for findings both within and beyond our solar system.
Chapter 11.1: The Structure of the Solar System
Grade 8 Integrated Science Chapter 11 Lesson 1; this is a short introduction into the structures of our solar system including basic units of measurement and introduction to our planets.
Space ressearch
Space research involves scientific studies carried out in outer space using specialized equipment. It began in earnest in the mid-20th century as rockets were developed that could overcome Earth's gravity. Some key early milestones included the first artificial object in space in 1944, the detection of the Van Allen radiation belts in 1958, and the first photos of the far side of the Moon in 1959. In the 1960s, important firsts included the first animal and first human, Yuri Gagarin, in space. Ongoing space research through the late 20th and early 21st centuries has involved missions to planets, asteroids, and other celestial bodies to learn more about the solar system and expand scientific knowledge.
Our Neighbours In Space
The document provides vocabulary and concepts related to science topics including space, the solar system, and chemistry. Key points covered include definitions of terms like satellite, orbit, radiation, and light year. Examples are given of different shapes like spherical, cylindrical, and conical. The solar system section lists the order of planets from the sun. Questions and answers are provided about space exploration milestones. Connectives are discussed for linking sentences, and examples are given of sentences using the passive voice.
Comet [autosaved]
The document provides information on 20 comets, including Halley's Comet, Comet McNaught, Comet Hyakutake, Comet Borrelly, Hale-Bopp Comet, Comet Chiron, Comet Wild 2, Comet Tempel-Tuttle, Comet Encke, Shoemaker-Levy 9, Comet Churyumov-Gerasimenko, Comet Leonard, Comet 103P/Hartley, Comet Donati, Comet Kohoutek, 'Oumuamua, Comet PanSTARRS, and others. It describes attributes like orbital period, size, discovery date, and notable appearances or impacts for each comet.
The Space Junk
The document discusses the issue of space debris and its negative effects. It outlines that there are over 3,000 defunct objects in Earth's orbit that are considered space junk. This debris poses a risk to active satellites and can also negatively impact the environment. When debris reenters the atmosphere, it can release chemicals that deplete the ozone layer and pollute oceans. The document examines existing policies from countries and organizations to regulate space debris and proposes potential solutions to mitigate the problem, such as using solar sails or electrodynamic tethers to remove debris from orbit.
