Rho Sagittarii : ウィキペディア英語版 | Rho Sagittarii
The Bayer designation Rho Sagittarii (Rho Sgr, ρ Sagittarii, ρ Sgr) is shared by two stars, ρ¹ Sagittarii and ρ² Sagittarii, in the constellation Sagittarius. The two stars are separated by 0.46° in the sky. Because they are close to the ecliptic, they 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. ==ρ¹ Sagittarii== Rho¹ Sagittarii (Rho¹ Sgr, ρ¹ Sagittarii, ρ¹ Sgr) is a spectral type F0 subgiant which has an apparent magnitude of +3.93. It is 122 light years from Earth.
