NGC 3625
Galaxy in the constellation Ursa Major
From Wikipedia, the free encyclopedia
NGC 3625 is an intermediate spiral galaxy in the constellation of Ursa Major. Its velocity with respect to the cosmic microwave background is 2,102±11 km/s, which corresponds to a Hubble distance of 101.1 ± 7.1 Mly (31.00 ± 2.18 Mpc).[1] However, five non-redshift measurements give a farther mean distance of 123.74 ± 5.12 Mly (37.940 ± 1.569 Mpc).[2] It was discovered by German-British astronomer William Herschel on 8 April 1793.[3][4]

NGC 3625 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.[5][6]
