* Rotation: The Sun rotates on its axis, completing a full rotation about once every 25 days at its equator. This rotation is observable through the movement of sunspots.

* Orbit: The Sun orbits the center of the Milky Way galaxy, taking about 225 to 250 million years to complete one orbit. This is known as the galactic year.

* Movement within the Milky Way: The Sun, along with the rest of the solar system, is also moving within the Milky Way galaxy's disk. This movement is not just in a circular path, but also a slightly wobbly one due to the gravitational influence of other stars and gas clouds.

Therefore, the Sun is constantly in motion, both rotating on its axis and orbiting the Milky Way galaxy.
