Galaxy in the constellation Cancer
From Wikipedia, the free encyclopedia
NGC 2565 is a barred spiral galaxy in the constellation of Cancer. Its velocity with respect to the cosmic microwave background for is 3,814±16 km/s, which corresponds to a Hubble distance of 183.5 ± 12.9 Mly (56.26 ± 3.95 Mpc).[1] Additionally, 34 non-redshift measurements give a distance of 169.79 ± 4.64 Mly (52.057 ± 1.422 Mpc).[2] It was discovered by German-British astronomer J. Gerhard Lohse (bio-fr) in 1886.[3]
