NGC 6622 is an interacting spiral galaxy in the constellation Draco.[1] It is located around 313 million light-years away, and it was discovered by Edward D. Swift and Lewis A. Swift on June 2, 1885.[1][2] NGC 6622 interacts with NGC 6621, with their closest approach having taken place about 100 million years before the moment seen now.[3] NGC 6622 and NGC 6621 are included in the Atlas of Peculiar Galaxies as Arp 81 in the category "spiral galaxies with large high surface brightness companions".[4][5]
NGC 6622 is the smaller of the two, and is a very disturbed galaxy.[5][1] The encounter has left NGC 6622 very deformed, as it was once a spiral galaxy.[6][1] The collision has also triggered extensive star formation between the two galaxies.[7] The most intense star formation takes place in the region between the two nuclei, where a large population of luminous clusters, also known as super star clusters, has been observed. At this region is observed the most tidal stress.[6][2] The brightest and bluest clusters are less than 100 million years old,[2] with the youngest being less than 10 million years old.[4] The side of the galaxy further from the companion features noticeably less star formation activity.[3][1][7]
