The other planets do have gravity.
The gravity of the Sun (or star) keeps them in orbit.
yes there are seasons like earth on other planets. Except, they all dont have the same tempuratures or the same period one or more season lasts.
i dont know i want to find this out too hehe
terrestrial
firstly why would we do that?
i dont now
Well Earth has many resources like oxygen there are many others too.
The Moon doesn't exactly float. The Moon actually "falls" towards Earth, meaning that without gravitation, it would continue in a straight line. Its almost circular orbit around Earth (instead of continuing in a straight line) is the direct result of Earth's gravitation.
Only the four outer planets have rings. The four inner planets (Mercury, Venus, Earth and Mars) dont have rings.
With gravity and inertia. If you dont know what those look them up in a scientific dictionary.
because of the earths gravity and constant attraction between sun and earth.
It would ruin the solar system and might destroy the other planets because they are in the way of the suns orbiting circle and all the planets would be floating in sapce all over the place or the sun and all the other planets will have to orbit the earth and it will become the earth system-dont think it's going to happen though
