Originally NGC 7320 was counted as part of Stephan's quintet, but in fact it is a foreground galaxy that may belong to the NGC-7331 group. NGC 7320 was discovered by French astronomer Édouard Jean-Marie Stephan on September 23, 1876.

Hickson 92 aka Arp 319, better known as Stephan's Quintet, is one of the most fascinating interactive galaxy groups in the sky and was also discovered by French astronomer Edouard Stephan in 1877. The group has a reputation for being particularly challenging to photograph.
The galaxies NGC 7317 to NGC 7319 form a spatially close interacting system at a distance of about 300 million light-years. Due to mutual gravitational effects, the spiral arms of the galaxies are irregularly deformed.

Stephan's Quintet is located in the northern part of the constellation Pegasus, only a few degrees from the border of the constellation Lizard.
