HIP 95168The Bayer designation Rho Sagittarii (ρ Sgr / ρ Sagittarii) is shared by two stars, ρ¹ Sagittarii and ρ² Sagittarii, in the constellation Sagittarius. The two stars are separated by 0.46° on the sky. Rho Sagittarii has the traditional Latin name "Cappa", meaning "cape" (worn by Sagittarius the Archer).

Because they are close to the ecliptic, these stars can be occulted by the Moon and very rarely by planets. The next occultation of ρ¹ Sagittarii by a planet will take place on 23 February, 2046, when it will be occulted by Venus.
