Description:

Antares (α Scorpii, α Sco, Alpha Scorpii) is a red supergiant star in the constellation de Scorpius. It is approximately 550 light-years from the Earth. It is the 16th brightest star (excluding to the Sun). Antares has a secondary, or companion star, Antares B (it is blue)…The companion is often described as green, but this is probably either a contrast effect or the result of the mixing of light from the two stars when they are seen together through a telescope and are too close to be completely resolved.
