You're close! Here's the correct way to understand how the Earth moves:

* The Earth spins on its axis. This rotation is what causes day and night.

* The Earth orbits around the Sun. This orbit takes about 365 days and is what causes the year.

So, the Earth doesn't spin "around" the Sun. It orbits it, following a path that's roughly circular.
