NGC 2545 is a barred spiral galaxy in the constellation of Cancer. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . Additionally, 15 non-redshift measurements give a closer distance of . It was discovered by German-British astronomer William Herschel on 11 January 1787.
NGC 2545 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. It is also a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.
NGC 2545 group NGC 2545 is a member of a group of galaxies named after it (also known as LGG 156). This group contains 5 galaxies, including NGC 2565, , , and CGCG 119-56.
Supernova One supernova has been observed in NGC 2545: SN 2008hn (TypeIc, mag. 18.4) was discovered by the Lick Observatory Supernova Search (LOSS) on 25 November 2008.
