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.
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 / ˈ æ k r æ b /, [8] though the International Astronomical Union now regards that name as applying only to the β Scorpii Aa component.
Nu Scorpii (ν Scorpii, abbreviated Nu Sco, ν Sco) is a multiple star system in the constellation of Scorpius. It is most likely a septuple star system, [5] consisting of two close groups (designated Nu Scorpii AB and CD) that are separated by 41 arcseconds. [5] Based on parallax measurements, [7] it is approximately 470 light-years from the Sun.
Lambda Scorpii is a triple star system and the second-brightest object in the constellation of Scorpius. It is formally named Shaula; Lambda Scorpii is its Bayer designation, which is Latinised from λ Scorpii and abbreviated Lambda Sco or λ Sco.
