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.
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.
Because it comes from other planets and earth is approx the same age as the other planets so they work it out bye the dust and how hot it is I think.
It can help us understand exactly why the Earth is fit to support life, while the planets we are capable of seeing are not.
The other planets do have gravity.
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.
Studying Earth allows scientists to understand fundamental planetary processes such as geology, atmosphere dynamics, and life forms. By extrapolating this knowledge to other planets, scientists can make comparisons and draw conclusions about similarities and differences, leading to a better understanding of the processes shaping those planets. Additionally, studying Earth helps scientists develop tools and techniques that can be used to analyze other planets from a distance.

It is estimated that the Solar System is 4.6 billion years old including Earth and the other planets.
Earth's scientist have not found life on other planets to date.
well some planets are bigger than the earth but from the inside earth is of course bigger than all of the other planets
