Xi Sagittarii

Encyclopedia : X : XI : XIS : Xi Sagittarii

The Bayer designation Xi Sagittarii (ξ Sgr / ξ Sagittarii) is shared by two stars, ξ¹ Sagittarii and ξ² Sagittarii, in the constellation Sagittarius. The two stars are separated by 0.46° on the sky.

Because they are close to the ecliptic, these stars can be occulted by the Moon and very rarely by planets. The last occultation of ξ² Sagittarii by a planet took place on 22 December, 1810, when it was occulted by Venus.
