The Aldebaran system is located some 65.1 light years away.  The two individual stars of the binary system orbit each other with a mean distance of 607 AU.  It was once thought that a nearby binary pair made up of a K5 and M2 dwarf were also part of the system, but in reality they are an optical binary (stars that visually appear to be part of a system but are not actually gravitationally bound to it), located much further away from our [[Solar System]].  The primary, Aldebaran A, is thought to possibly have a gas giant in close orbit.

Because Aldebaran is located near the [[ecliptic]], it is regularly occulted by the [[Moon]] near the time of the autumn equinox, with the next occurrence happening in 2015.  It is this occultation that originally allowed for the accurate measurement of Aldebaran's size. <ref>http://adsabs.harvard.edu/full/1979AJ.....84..872W</ref>
