The planets were formed by the Big Bang Theory, which was when all sorts of gases combined in one place, and a huge explosion occurred. Rocks formed, over a million of years they cooled down, and became planets, that was considered billions of years before any life was in the universe. Because of the Big Bang theory the universe will still expand, making new planets form!!!
totally different than any other planets. The temperature
rises to 450 degrees Celsius, and at night it
goes to -180 degrees Celsius. Mercury is 58 million
kilometers away from the sun
and orbits around the sun for 88
days. Mercury’s equator is about 3,024 miles,
and it takes 58.6 days to turn on its axis.
There is cliffs which are 2
miles high, it shows that this had been
formed three billion years ago. Its surface is
filled with thousands of craters which was made of
meteors crashing into Mercury.
Venus is a very interesting planet. Its
about the same size as Earth, and much
hotter than Mercury with about a difference
of 30 degrees Celsius.
The distance from the
sun is 108 million kilometers, and
255 days to have a full
circle around the sun, its equator is
about 7.504 miles, and it takes 243 days to
Turn on its axis. Its very
hard to see through the clouds
of Venus, they almost kept every
part of Venus hidden. The most
interesting part is that Venus actually
has thousands of volcanoes, and they may be
erupting right now!
Our Home Planet
Earth is the is the biggest rocky planet in
the Solar System, and also the only planet that
has life on it, at least
that what we know until
now. Earth is similar to
other planets, it has
craters, which is similar to
Mercury, and it has similarities
with Venus such as the volcanoes. Earth is
150 million kilometers from the sun, and orbits
around for 365 days. Its equator is 7,909
Miles. Earth is the nearest planet to the sun
which has a moon orbit around it. Earth has
about 70% of water, that’s one of the reasons we can
live in this planet. Also Earth has 21% oxygen
, and 78% nitrogen, all sorts of organisms
depend on them.
If you saw Mars you would say its a
desert while its much
bigger than that. The
Atmosphere is mainly
carbon dioxide. The
temperatures rise to
20 degrees Celsius, but
usually it lowers lesser
than -23 degrees Celsius.
Mars billion years ago it was very different
, the atmosphere was much more thicker, there
was erupting volcanoes, and there is several
volcanoes now located in the northern
hemisphere, but there are not erupting no longer. Some
Astronomers believe there would be microscopic
Organisms living there from the many similarities it
has like Earth ! Mars's equator is 4,213 miles
,and 228 million kilometers from the sun. It takes 24.6
hours to spin on its axis, and it takes 1.88 years to
orbit the sun. Mars got two moons.
Jupiter is the largest planet
in our Solar System. The
planet has winds that goes
to 400 kilometers per hour!
It has amazing clouds, which
are made of frozen water
crystals, its atmosphere is
made of helium, and
hydrogen. If you compare
Earth with Jupiter, Jupiter
would be 11 times bigger!
Jupiter’s gravity is very strong
because of it’s humongous mass. It has
a thin unclear ring around it, and made of
fine dust! Jupiter’s equator is 88.650 miles,
482 million miles from the sun, It takes
9.9 hours to spin on its axis, and it takes
11.8 years to have a full orbit around the sun.
Jupiter has 28 moons!
Saturn is second largest planet in the Solar
System. It consists of liquid and gas. Saturn
has fierce winds that
goes 992 miles per hour.
Saturn has extraordinary
rings they consist of rock,
frozen water, and dust altogether.
About every 5 years the position of
Saturn changes, it goes up then down.
Its equator is 80,389 miles, 885 million miles
from the sun, 10.5 hours to spin on its axis,
It takes 24.46 years to orbit around the sun
, and it has at least 33 moons attached to it.
Uranus as you can
see its rings are
upside down, but its
Not only the rings,
so as Uranus!
made that the planet
could have had a
collision in the period of
The planets’ formation. Uranus’s rings are
very dark, and consists of boulders.
Uranus’s atmosphere is
made of hydrogen, and helium.
Uranus’s equator is 31,693 miles,
1.8 billion miles from the sun, 17.2 hours
To spin on its axis, it takes 84.01 years
To orbit the sun, and it has 21 moons.
Neptune is very similar
to Uranus, its also the
most distant planet
from the sun. Neptune’s
rings are narrow, and
dark. The clouds in there
are constantly changing.
Neptune, and Uranus both
colored blue because of the
non smelling gas called methane
Neptune’s equator is 30,710,2.8
billion miles from the sun it takes 16.1
hours to spin on its axis, and 165.8 years
To orbit around the sun. It got 8 moons.
The terrestrial planets
are as shown in the
Venus, Earth, and
Mars. You can as well
say they are rocky
planets. They all have
rocky surfaces, and
most of them are similar
to each other in many ways.
Venus has volcanoes like Earth, and
Mars, which is not active in Mars.
Earth has craters like Mercury, and other
many other similarities they share.
Jovian planets are
also known as the Gas
Giants. They are;
Uranus. These are
the largest planets
in the solar system. Like
The terrestrial planets all
of them have common
things. They all have rings.
Neptune, and Uranus are like twins
for all the similarities they have in
common. Jupiter and Saturn share about
The same size in the equator.
Pluto is not a Planet!!!
I am sure you have
why I did not
mention Pluto, when
I described each
planet. I did that
because Pluto is no
longer a planet! That
decision was made in
the summer of 2006,
when all astronomers
gathered, and made a new
definition for the word “planet”
which is that a planet must go
around the planets in a circler orbit.
Unfortunately, Pluto didn’t have one
instead it had an elliptical orbit. That
demoted Pluto from being a planet!
Rings Formation on planets
The cause of rings becoming formed
is still confusing. Hypotheses said that it happens if a moon or any size that is similar comes too near to a Planet its gravity’s strength tears it into lots of pieces then it keeps orbiting its planets. Earth cannot have rings, because even if it had the moon would tear it apart first. That was what astronomers think that this might be the way the rings were formed.
