This is a bit of a tricky question because it plays on our natural understanding of the world. Here's the breakdown:

* The Sun Doesn't Go Around the Earth: The Earth revolves around the Sun. It takes approximately 365.25 days for the Earth to complete one full orbit around the Sun.

* Day and Night: What we perceive as the Sun going around the Earth is actually the Earth rotating on its axis. A full rotation takes about 24 hours, causing day and night.

So, to answer your question directly, the Sun doesn't go around the Earth. The Earth rotates on its axis and revolves around the Sun.
