NGC 2325 is an elliptical galaxy in the constellation of Canis Major. Its velocity with respect to the cosmic microwave background is 2,356±25 km/s, which corresponds to a Hubble distance of 113.4 ± 8.1 Mly (34.76 ± 2.48 Mpc). However, 16 non-redshift measurements give a much closer mean distance of 74.53 ± 3.94 Mly (22.850 ± 1.209 Mpc). It was discovered by British astronomer John Herschel on 1 February 1837.

NGC 2325 is a radio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure. It also has an 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 group

NGC 2325 is a member of a galaxy group known as [CHM2007] HDC 421. The group contains at least eight galaxies, including IC 456, ESO 427-22, MCG-05-17-006, MCG-05-17-004, MCG-05-17-008, and two others.
