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 39.08 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 6.9 kpc, while NGC 7541 has two tidal tails. They have a projected separation of 44 kpc.

A Type II supernova designated SN 2002gd was detected by multiple independent observers beginning October 5, 2002. It was positioned $2,888 km/s$ east and $34 arcsecond$ north of the galactic nucleus of NGC 7537.
