Rho Scorpii (ρ Scorpii, abbreviated Rho Sco, ρ Sco) is a double star in the constellation of Scorpius. It has an apparent visual magnitude of +3.87, which is bright enough to be seen with the naked eye. Based upon parallax measurements, it is located approximately 472 light years from the Sun.[1] At that distance, the visual magnitude of the system is reduced by 0.07 due to extinction from interstellar dust.[10] It is a member of the Upper Scorpius OB association.[11]
It has two components, designated Rho Scorpii A and B. Rho Scorpii A is itself a single-lined spectroscopic binary whose components are designated Rho Scorpii Aa (formally named Iklil/ˈɪklɪl/, traditionally the name for several neighboring stars)[12] and Ab.
