Moon:

* The Moon rotates on its axis once every 27.3 days, which is the same amount of time it takes to orbit the Earth. This is why we always see the same side of the Moon. This synchronous rotation is caused by tidal forces from Earth.

Sun:

* The Sun rotates on its axis, but it doesn't rotate at a uniform rate. The Sun is a giant ball of gas, and its rotation is differential, meaning that different parts of the Sun rotate at different speeds.

* At the equator, the Sun completes a rotation in about 25 days. Near the poles, the rotation period is about 36 days.
