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]

According to A. M. Garcia, NGC 3087 is part of the six member NGC 3038 Group (also known as LGG 184). The other five galaxies are NGC 3038 [fr], NGC 3120, IC 2532 [fr], ESO 373-21 [d], and ESO 373-26 [d].[3]
