well, other planets have properties such as gases which life forms or organisms can't live in or they would die.
There are probably millions of them. We have only found one so far. The problem with inhabitable planets other than the Earth is they're so far away.
If you think about it across the whole entire universe out of the Milky Way and beyond ther must be at least 1 other inhabitable planet. They might not be like us they might have 4 legs and 7 arms!?! Who knows? In 2016 a special telescope will be in use and is x10 more accurate so we might find another planet one day!
Studying the earth helps scientists to understand other planets since the earth is part of the solar system. Scientists use the features of the earth to compare them with what other planets hold.
Differentiation occurred in other inner planets, besides Earth.
Yes, the Earth and other planets in our solar system revolve around the Sun in elliptical orbits due to the force of gravity. This orbital motion is what causes the planets to move in their respective paths around the Sun.
All but the Earth. It is inhabitable but the others are not so.

The constellation itself may have undiscovered planets around one of the stars that may turn out to be inhabitable, but we have no current knowledge of an inhabitable planet in that vicinity, or around any of the individual stars that make up that constellation.
The other planets do have gravity.

Since no one from Earth has visited another planet, and we have no indication that there is anyone on the other planets, Earth does not help other planets in any way. Why do you think there is something Earth does to help them- whoever them is.
Earth and the other planets are mostly made of rock.
Astronomers have found Earth-sized planets in other solar systems.
No, other planets are rotating at other speeds.

It is estimated that the Solar System is 4.6 billion years old including Earth and the other planets.
