1) Revolve: Is when a planet orbits around another planet or a
star.
2) Rotate: This is when a planet or a star spins on its
axis.
3) There are now 8 planets found in the solar system.
4) Mercury, Venus, Earth, and Mars are the inner planets.
5) Jupiter, Saturn, Uranus, and Neptune are the outer
planets.
6) The inner planets are inside the asteroid belt while the
outer planets are outside of the asteroid belt and are very far
from the sun.
7) The inner planets have more craters than the outer planets
because the sun is using its gravity to pull comets towards the
inner planets and also the inner planets are closer to the asteroid
belt.
8) Orbit: A specific path followed by a planet, satellite,
etc.
9) It has to orbit the sun, have to have enough gravity to pull
itsel to a spherical shape, and it needs to have nothing in its
orbit.
10) Dwarf Planets are objects not as big as a planet but not
too small to be considered a meteor.
11) Ceres, Eris, and Haumea are the three dwarf planets.
3. Mercury
1) The sun causes Mercury to have no
substancialatmosphere.
2) Helium and Sodium is composed in Mercurys atmosphere.
3) The three processes which shaped Mercury are the impact
cratering, volcanism, and tectonic activity.
4. Venus
Venus is referred to be a evening star because it is the most
brightest planet viewed from Earth.
Venuss atmosphere contains carbon dioxide and sulfuric
acid.
Retrograde rotation is when it rotates in a clockwise
direction.
Since the rotation is also very slow it takes longer for a day
than a year.
The sun will rise in the west if you were in Venus because it
is rotating clockwise.
Venus is the hottest planet in the solar system because carbon
dioxide and the sulfuric acidtraps the heat from getting out.
5. Earth
The atosphere contains 21% oxygen, 78% nitrogen, 0.9% Argon,
and the other 0.1 are other types of air.
The atmosphere absorbs harmful radiation and also protects us
from meteors.
The rotational tilt of the Earth is 23.5degrees.
The core has a molten iron-nickel which causes the magnetic
field around the Earth.
The Earth only has one satellite called the Moon.
6. Mars
In mars ancient bacteria are found in their meteorites which
makes the scientists think that there are signs of life in
mars.
Carbon Dioxide is the primary element in the atmosphere of
Mars.
Mars has soils rich in iron-laden clay which makes Mars have a
Reddish-Orange color.
Olympus Mons is a 600km tall mountain in Mars.
Mars have two small satellites called Phobos and Deimos.
7. Jupiter
Jupiters fast rotation causes Jupiter to flatten at the poles
and bulge in the equator.
Jupiters atmosphere contains hydrogen, helium, sulfur, and
nitrogen.
A Great Red Spot is a hurricane like storm which lasts very
long.
63 satellites are found in Jupiter.
Io is a satellites of Jupiters which has volcanically
Active.
8. Saturn
Saturns atmosphere contains hydrogen and helium.
Astronomers believe the rings developed from particles that
resulted from the break-up of naturally occurring satellites.
The compositions of the rings are ice, rock, and a bit of
gas.
Saturn has a very small density making itself able to
float.
Saturns Season is long as 7 years.
9. Uranus
Uranus rotates in its side.
Hydrogen, helium, and methane makes up Uranuss atmosphere.
Uranus have 27 known satellites.
10. Neptune
Neptunes atmosphere is made up of ammonia, helium, and
methane.
Neptune has 13 known satellites.
The largest satellite is Triton. Scientists think Triton was
not originally Neptunes Moon. They theorize that Triton was
captured by Neptune's gravitational pull, forcing it into an orbit
around the planet.
11. Pluto
Plutos three moons are called Charon, Nix, and Hydra.
Scientists learned that Pluto had Methane Frost using a
spectroscope.
Charon had water frost and sometimes appeared more blue than
Pluto.
12. Ceres
It takes 4.6 Earth Years to have Ceres have one complete
revolution.
Ceres was once considered an asteroid because it was orbiting
between Jupiter and Mars.
Ceres has a rocky core and a icy mantle. .
13. Eris
Eriss original name was Xena.
It takes 557 Earth years for Eris to orbit once.
Eris has a moon named Dysnomia.
Eris is not considered a planet because it does not clear out
its orbit.
