NGC 7337


NGC 7337 is an barred spiral galaxy in the constellation of Pegasus. Its velocity with respect to the cosmic microwave background is, which corresponds to a Hubble distance of. It was discovered by Irish physicist George Stoney and William Parsons, 3rd Earl of Rosse, on 10 September 1849.
NGC 7337 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.

Galaxy Groups

NGC 7337 is a member of a visual grouping known as the NGC 7331 Group of galaxies. The members of the group, NGC 7335, NGC 7336, NGC 7337, and NGC 7340, lie far in the background at distances of approximately 300–350 million light years, compared to the group's main galaxy NGC 7331, which is much closer at a distance of approximately 44 million light years.
All of the members of the NGC 7331 Group, along with NGC 7325, NGC 7326, NGC 7327, NGC 7333, NGC 7338, are listed together as Holm 795 in Erik Holmberg's A Study of Double and Multiple Galaxies Together with Inquiries into some General Metagalactic Problems, published in 1937.
