Alpha Centauri is a star in the constellation Centaurus and the third brightest in the sky.[6] Alpha Centauri is a double star system consisting of Alpha Centauri A and Alpha Centauri B. At 4.32 light years from Earth, it is one of the closest stars to the Solar System. Proxima Centauri is slightly closer to the Solar System than these 2 stars.
It was popular in science fiction and was the destination of the space traveling family in the TV show from the 1960s Lost in Space.
