description Overview

Spica

Spica, designated Alpha Virginis, is the brightest star in the constellation of Virgo and a prominent binary star system. Located approximately 250 light-years from Earth, the system consists of two massive B-type stars orbiting so closely that their mutual gravity distorts them into ellipsoidal shapes, causing variations in observed brightness. The primary star is a rotating ellipsoidal variable...
