NGC 7537 is a spiral galaxy located in the equatorial constellation of Pisces, about 1.5° to the NNW of Gamma Piscium.[7] It was first documented by German-born astronomer William Herschel on Aug 30, 1785. J. L. E. Dreyer described it as, "very faint, considerably small, round, brighter middle, southwestern of 2".[8] This galaxy lies at a distance of approximately 127 Mly (39 Mpc) from the Milky Way,[3] and is a member of the Pegasus I cluster.[4]

This object forms a pair with the nearly edge-on barred spiral galaxy NGC 7541, and the two show signs of interaction. NGC 7537 has a curved tidal tail to the northeast with a length of 23 kly (6.9 kpc), while NGC 7541 has two tidal tails. They have a projected separation of 140 kly (44 kpc).[6]

A Type II supernova[9] designated SN 2002gd was detected by multiple independent observers beginning October 5, 2002. It was positioned 34″ east and 8″ north of the galactic nucleus of NGC 7537.[10]
