Extensive Definition

For the fallen angel Aldebaran, see Aldebaran (demon); and distinguish from Alderaan (astronomy).
Aldebaran is the brightest star in the constellation Taurus and one of the brightest stars in the nighttime sky. It has the Bayer designation Alpha Tauri. Because of its location in the head of Taurus, it has historically been called the Bull's Eye. Aldebaran has the appearance of being the brightest member of the more scattered Hyades cluster, which is the closest star cluster to Earth. However, it is merely located in the line of sight between the Earth and the Hyades, and is actually an independent star. NASA's Pioneer 10 spacecraft, which flew by Jupiter in 1973 will reach and pass by Aldebaran in about two million years
In 1997, a possible substellar companion was reported, with a mass at least 11 times that of Jupiter with an orbital period of around 2 years, however this has not been confirmed.
