Here's the breakdown:
* Proxima Centauri is the closest star to our Sun.
* It's part of a triple star system called Alpha Centauri.
* The other two stars in the system are Alpha Centauri A and Alpha Centauri B, which are a binary pair.
While Proxima Centauri is the closest star to us, it's actually quite faint and difficult to see with the naked eye. Alpha Centauri A and B, on the other hand, are bright enough to be seen from Earth.
