NGC 2545

Galaxy in the constellation Cancer From Wikipedia, the free encyclopedia

NGC 2545 is a barred spiral galaxy in the constellation of Cancer. Its velocity with respect to the cosmic microwave background is 3,613±16 km/s, which corresponds to a Hubble distance of 173.8 ± 12.2 Mly (53.29 ± 3.74 Mpc).[1] Additionally, 15 non-redshift measurements give a closer distance of 158.97 ± 11.44 Mly (48.740 ± 3.507 Mpc).[2] It was discovered by German-British astronomer William Herschel on 11 January 1787.[3][4]

Close

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.[5][6] It is also a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.[1]

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, UGC 4308 [d], CGCG 119-44 [d], and CGCG 119-56.[7][8]
