==Star System==

Acrux itself is actually a multiple star system of three known stars, located 325 light years away.  Two of the stars of the Acrux system make up a [[Binary_stars#Visual_Binaries|visual binary]], and are commonly referred to as '''Alpha-1''' and '''Alpha-2''' respectively.  The two stars have a separation of at least 430 AU and take a minimum of 1500 years to complete an orbit of each other.  Furthermore, Alpha-1 itself is a [[Binary_stars#Spectroscopic_Binaries|spectroscopic binary]] star.  From an observer on [[Earth]], there is another star located on 90 arcseconds from the triple stars of the Acrux system and has the same proper motion in space.  If this additional star is part of the system, it would have an orbital distance of 9000 AU from the other stars in the system.  However it is likely the star is just an optical binary and not part of the system at all, and many be significantly more distant star that is along the same line of sight.
