Here's why:
* The Sun is the center of our solar system. All the planets, including Earth, orbit around the Sun due to its massive gravity.
* The Sun is also moving. It's not stationary but is actually orbiting the center of our Milky Way galaxy, taking about 225-250 million years to complete one orbit. This motion is caused by the combined gravitational pull of all the stars and other matter in the galaxy.
So, while the Sun doesn't orbit a specific object like a planet, it's constantly in motion within the larger context of the Milky Way galaxy.
