Omicron Sagittarii (ο Sgr / ο Sagittarii) is a binary star in the constellation Sagittarius. It also has the traditional name Manubrij or Manubrium, from a Latin word meaning handle, or haft. ο Sagittarii is located 139 light years from Earth.
ο Sagittarii is a spectral type K0 orange giant and has an apparent magnitude of +3.77. It has a faint, 13th magnitude companion, ο Sagittarii B, 36 arc seconds away.
Because it is close to the ecliptic, ο Sagittarii can be occulted by the Moon and very rarely by planets. The last occultation of ο Sagittarii by a planet took place on 24 December 1937, when it was occulted by Mercury.[citation needed]
