Question

what is a planet.what is the uses of it .what are there in the plants

Answer 1

Answer:

A planet is a large object such as Jupiter or Earth that orbits a star. Planets are smaller than stars, and they do not produce light. ... A star and everything which orbits it are called a star system. There are eight planets in our Solar System.

You could argue the use of Earth is to support human and other life. Currently all other known planets have only the use to keep astronomers, astrophysicists and other scientists busy.
