Rho1 Arae is the Bayer designation for a star in the southern constellation of Ara. Unusually for a star with a Bayer designation it was not catalogued by Bayer in his Uranometria. It was instead first catalogued by Nicolas Lacaille in his Coelum Australe Stelliferum published in 1763. This star gained the Bayer designation of Rho1 Arae in Bode’s Uranographia published in 1801.
