This object forms a pair with the nearly edge-on barred spiral galaxyNGC 7541, and the two show signs of interaction. NGC 7537 has a curved tidal tail to the northeast with a length of 23kly (6.9kpc), while NGC 7541 has two tidal tails. They have a projected separation of 140kly (44kpc).[6]
SN 2002gd (Type II, mag. 16.7) was discovered by Alain Klotz, and independently by Tim Puckett and Alex Langoussis on October 5, 2002.[9][10][11] It was positioned 34″ east and 8″ north of the galactic nucleus of NGC 7537.
