Question

We have listen many times that the sun rotate on it's axis but the planets are revoling around how it's possible plz explain

Answer 1

The sun rotates about its axis and does not change its position.
The planets REVOLVE around the sun. The sun does not move, it is the planets that move.

Answer 2

the sun rotate on its own axis and foes not change its position. the planets also rotate on their own axis and they also revolve around the sun as the sun exerts a gravitational pull which holds on all these planets. if this gravitational pull would not have been there then all these planets would have pursue a uniform straight motion and have gone somewhere else in this universe.

hope this helps you.
