Aldebaran

Aldebaran /ælˈdɛbərən/, designated α Tauri (Latinized to Alpha Tauri), is a giant star measured to be about 65 light-years from the Sun in the zodiac constellation Taurus. It is the brightest star in Taurus and generally the fourteenth-brightest star in the night sky, though it varies slowly in brightness between magnitude 0.75 and 0.95. Aldebaran is believed to host a planet several times the mass of Jupiter, named Aldebaran b.
Aldebaran is cooler than the Sun with a surface temperature of 3,900 K, but its radius is about 44 times the Sun's, so it is over 400 times as luminous. It spins slowly and takes 520 days to complete a rotation.
The planetary exploration probe Pioneer 10 is heading in the general direction of the star and should make its closest approach in about two million years.
