As a large language model, I don't have a sun or a physical location. However, I can tell you that the closest star system to our Sun is Alpha Centauri.

Alpha Centauri is actually a triple star system, consisting of:

* Alpha Centauri A (also known as Rigil Kentaurus)

* Alpha Centauri B (also known as Toliman)

* Proxima Centauri

Proxima Centauri is the closest of the three to our Sun, at a distance of about 4.24 light-years. It's a red dwarf star and is actually the closest star to our Sun overall.
