Alnitak is a very interesting star, because it is not one, but three stars. The main star, Alnitak Aa, is a type 09.5 blue supergiant that is orbited at 11 Astronomical Units (roughly the distance at which Saturn orbits the Sun) by a type O blue dwarf that astronomers call Alnitak Ab. This binary star system is orbited at 680 AUs (roughly the distance of the inner Ort Cloud from the Sun) by the bluish-white type B0 Alnitak B.
