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]
One supernova has been observed in NGC 3087: SN 2023mdv (Type Ia, mag. 18.323) was discovered by ATLAS on 29 June 2023.[3]
NGC 3038 Group
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, NGC 3120, IC 2532, ESO 373–21, and ESO 373–26.[4]
