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]
