NGC 2169 is an open cluster of stars in the Constellation of Orion.[1] It was possibly discovered by Giovanni Batista Hodierna before 1654 and independently discovered by William Herschel on October 15, 1784.[2] NGC 2169 is at a distance of about 3,600 light years away from Earth. It is nicknamed "The '37' Cluster" due to its striking resemblance to the numerals "37".[3] The cluster is composed of components Collinder 38, a I3pn open cluster,[4] and Collinder 83, a III3m open cluster.
