The Sun rotates on its axis, but it's not a solid body like Earth. Instead, it rotates differentially, meaning different parts of the Sun rotate at different speeds.

Here's a breakdown:

* Equator: The Sun's equator rotates roughly once every 25 days.

* Poles: The Sun's poles rotate much slower, taking about 36 days to complete a rotation.

So, there isn't a single "complete rotation" time for the Sun. It depends on the latitude you're considering.
