A bright red star in the constellation Scorpius, one of the brightest stars visible from Earth.
From Greek 'anti-Ares' (opposite Mars), named because of its reddish color similar to the planet Mars. Ancient Greek astronomers named it as a rival to the war god's planet.
Antares means 'rival to Mars' in Greek, and when you look at it through a telescope, you see it's actually a red supergiant star so huge that if placed where our Sun is, it would swallow Mercury, Venus, Earth, and Mars—talk about living up to its name as something mighty.
