they all have cells, chlorophyl and other parts, look it up is the best way
anyway they are alike because they have the rotation around the sun, and that is what gives them time to go around!! And there are four planets each, and they are all plantes(; haha
None of the inner planets have rings.
You can see all the plantes and stars and some of the gas comprising the milky way
The four outer planets, also known as gas giants, are Jupiter, Saturn, Uranus, and Neptune. They are all composed mainly of hydrogen and helium, and do not have solid surfaces like the inner rocky planets. They also have large and complex ring systems and numerous moons orbiting around them.
Jupiter can fit
The inner planets Mercury, Venus, Earth, Mars are are all relatively small, they are all rocky, they all have a relatively thin atmosphere.
They are all compact objects with rocky, accessible surfaces.
Go to Imbd.com it tells you all of the stars. Or all of the chacters from the other movies. Im on the 6th book.
# They are made of rock # They do not posses rings
they are all soild masses and mecury, venus, earth, mars
Well you can unlock most of them easily in the Subspace Emissary.
Relatively small (compared to the gas giants); rocky; dense.
