NGC 3087 is an elliptical galaxy in the constellation of Antlia. Its velocity with respect to the cosmic microwave background is 2987 ± 30 km/s, which corresponds to a Hubble distance of 44.05 ± 3.13 Mpc (∼144 million light-years).[1] It was discovered by British astronomer John Herschel on 2 February 1835.[2]
