NGC 7537

NGC 7537 is a spiral galaxy located in the equatorial constellation of Pisces, about 1.5° to the NNW of Gamma Piscium. 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". This galaxy lies at a distance of approximately 127 Mly (39 Mpc) from the Milky Way, and is a member of the Pegasus I cluster.

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).

A Type II supernova 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.
