NGC 1901 is an
open cluster in the
DoradoConstellation. It has a bright middle and is a little rich, with stars from 7th magnitude downwards. The celestial object was discovered on 30 December 1836 by the
BritishastronomerJohn Herschel.[5] The cluster is sparsely populated with
GAIA data suggesting a membership of around 80 stars.[6] It is considered unlikely it will survive its next pass through the
Milky Way’s galactic plane in about 18 million years time.[6]
