That's a bit of a trick question! The Sun is a star. It's the closest star to Earth, and it's the one that provides us with light and heat.

It's possible that you're thinking of the difference between the Sun and other stars:

* The Sun is our star. It's the only star in our solar system.

* Other stars are distant. We see them as points of light in the night sky, even though they're giant balls of burning gas just like the Sun.

So, while the Sun is a very special star to us because of its proximity, it's still a star just like all the others.
