'''NGC 2169''' is an [[open cluster]] in the [[Orion constellation]]. It was possibly discovered by [[Giovanni Batista Hodierna]] before 1654 and discovered by [[William Herschel]] on October 15, 1784.<ref>{{cite book|last=O'Meara|first=Stephen James|title=Deep Sky Companions: Hidden Treasures|date=2007|publisher=[[Cambridge University Press]]|isbn=9780521837040|pages=180}}</ref> NGC 2169 is at a distance of about 3,600 [[light year]]s away from [[Earth]]. It is nicknamed "The '37' Cluster" due to its striking resemblance to the numerals "[[37 (number)|37]]".<ref>{{cite web|work=Constellation Guide|url=http://www.constellation-guide.com/constellation-list/orion-constellation/|title=Orion Constellation|accessdate=2014-03-03}}</ref> The cluster is composed of components ''Collinder 38'', a I3pn open cluster,<ref>{{cite web|work=Backyard Astronomy for Amateur Astronomers|url=http://www.backyard-astro.com/Logs/ngc2169.html|title=Collinder 38|archiveurl=https://web.archive.org/web/20160414061459/http://www.backyard-astro.com/Logs/ngc2169.html|archivedate=2016-04-14|accessdate=2014-03-03}}</ref> and ''Collinder 83'', a III3m open cluster.
