NGC 2986
Galaxy in the constellation Hydra
From Wikipedia, the free encyclopedia
NGC 2986 is an elliptical galaxy in the constellation of Hydra. Its velocity with respect to the cosmic microwave background is 2,637±24 km/s, which corresponds to a Hubble distance of 126.8 ± 9.0 Mly (38.89 ± 2.75 Mpc).[1] Additionally, 18 non-redshift measurements give a distance of 116.31 ± 8.30 Mly (35.661 ± 2.544 Mpc).[2] It was discovered by German-British astronomer William Herschel on 10 March 1785.[3][4]
