NGC 6622is aninteractingspiral galaxyin theconstellation Draco.[1]It is located around 313 millionlight-yearsaway, and it was discovered byEdward D. SwiftandLewis A. Swifton 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 theAtlas of Peculiar Galaxiesas 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 extensivestar formationbetween the two galaxies.[7]The most intense star formation takes place in the region between the two nuclei, where a large population of luminousclusters,also known assuper star clusters,has been observed. At this region is observed the mosttidal 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]
