It's not quite accurate to say planets "rotate" around the sun. The correct term is revolve.

Here's the breakdown:

* Rotation: This refers to an object spinning on its own axis. Earth rotates on its axis, which is why we have day and night.

* Revolution: This refers to an object moving in an orbit around another object. Planets revolve around the sun.

So, to answer your question: Planets revolve around the sun.
