Antares is the brightest and most evolved stellar member of the Scorpius–Centaurus association, the nearest OB association to the Sun. It is located about 170 parsecs (550 ly) from Earth at the rim of the Upper Scorpius subgroup, and is illuminating the Rho Ophiuchi cloud complex in its foreground.
Scorpius is a zodiac constellation located in the Southern celestial hemisphere, where it sits near the center of the Milky Way, between Libra to the west and Sagittarius to the east. Scorpius is an ancient constellation whose recognition predates Greek culture; [ 1 ] it is one of the 48 constellations identified by the Greek astronomer Ptolemy ...

The Scorpius–Centaurus association (sometimes called Sco–Cen or Sco OB2) is the nearest OB association to the Sun. This stellar association is composed of three subgroups (Upper Scorpius, Upper Centaurus–Lupus, and Lower Centaurus–Crux) and its distance is about 130 parsecs or 420 light-years.

SIMBAD. data. Sigma Scorpii (or σ Scorpii, abbreviated Sigma Sco or σ Sco), is a multiple star system in the constellation of Scorpius, located near the red supergiant Antares, which outshines it. This system has a combined apparent visual magnitude of +2.88, [2] making it one of the brighter members of the constellation.
Tau Scorpii, Latinized from τ Scorpii, formally known as Paikauhale / ˌ p aɪ k aʊ ˈ h ɑː l eɪ /, is a star in the southern zodiac constellation of Scorpius.The apparent visual magnitude of Tau Scorpii is +2.8, [2] while parallax measurements yield a distance estimate of roughly 470 light-years (150 parsecs) from Earth.
Sagittarius famously points its arrow at the heart of Scorpius, represented by the reddish star Antares, as the two constellations race around the sky. Following the direct line formed by Delta Sagittarii (δ Sgr) and Gamma2 Sagittarii (γ 2 Sgr) leads nearly directly to Antares.
Beta Scorpii (β Scorpii, abbreviated Beta Sco, β Sco) is a multiple star system in the southern zodiac constellation of Scorpius. It bore the traditional proper name of Acrab / ˈækræb /, [8] though the International Astronomical Union now regards that name as applying only to the β Scorpii Aa component.
