Arp 87
Arp 87 is a pair of interacting galaxies, NGC 3808A and NGC 3808B. They are situated in the Leo constellation. NGC 3808A, the brighter, is a peculiar spiral galaxy, while NGC 3808B is an irregular galaxy.
The two galaxies were discovered on 10 April 1785 by William Herschel. The two are located about 330 million light-years away from the Earth. Arp 87 was observed by the Hubble Space Telescope in 2007, which revealed massive clouds of gas and dust flowing from one galaxy to another. Additionally, both galaxies appear to have been distorted.
Arp 87 is an isolated member of the Coma Supercluster.
One supernova has been observed in NGC 3808A: SN2013db was discovered by Robert Gagliano, Jack Newton, and Tim Puckett on 29 May 2013.
