EspañolXI SAGITTARII
(Redirected from Xi2 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. The star ξ² Sagittarii in particular carries the proper name 'Nergal', which is the name of an Assyrian or Babylonian deity that was portrayed within parts of Sagittarius.
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.
'Xi-1 Sagittarii' is a spectral type B9.5 supergiant which has an apparent magnitude of +5.08. It is at least 2300 light years from Earth.
'Xi-2 Sagittarii' is a spectral type G8 or K0 giant which has an apparent magnitude of +3.52. It is 372 light years from Earth.
