It is a blue subgiant star located at a distance of 262 light years from Earth. Spica is really a close binary star system. It is one of the nearest massive binary stars to the solar system.
The name Spica (pronounced /ˈspaɪkə/) comes from the Latin phrase spīca virginis, meaning “Virgo’s ear of grain.” The Latin word spicum refers to the ear of wheat Virgo holds in her left hand. In Greek and Roman mythology, the constellation and the star were associated with Demeter (Ceres), the goddess of the harvest.
