Rotation:
* The Sun rotates on its axis. However, it's not a solid body like Earth, so different parts rotate at different speeds. The equator rotates about once every 25 days, while the poles take about 36 days to complete a rotation.
* This rotation is evident in sunspots, which appear to move across the Sun's surface.
Revolution:
* The Sun doesn't revolve around anything in the way planets do. The Sun is the center of our solar system, and the planets, including Earth, revolve around it.
* The Sun *does* move, however, along with our solar system, orbiting the center of the Milky Way galaxy. This journey takes about 230 million years to complete.
In summary:
* The Sun rotates on its axis, but different parts rotate at different speeds.
* The Sun is the center of our solar system and doesn't revolve around anything in the way planets do.
* The Sun, along with our solar system, revolves around the center of the Milky Way galaxy.
