The star we see as Alpha Centauri is actually two stars designated A and B, which move around each other over a period of 80 years in an eccentric orbit - at their closest their separation is the same as Saturn from the Sun.
The stars themselves are not unlike our own Sun but a third member of the system - Proxima Centauri - is a feeble dwarf star.
Alpha and Beta Centauri are famous for pointing the way to the celebrated Southern Cross.
