Messier 39 (also known as M39, or NGC 7092) is an open cluster in the constellation of Cygnus.[3] It was discovered by Charles Messier in 1764. M39 is at a distance of about 326 pc (1,060 ly)[1] from Earth whose age is estimated to be from 278 million years.[1]
It is located in the sky at Right Ascension 21h 32.2m, and Declination +48° 26′, with a total magnitude (brightness) of 5.5 and size of 29 (arcmin) across.[2] Stellar population of this loose open cluster is about 30 members.[2]
