NGC 5032 is a barred spiral galaxy in the constellation of Coma Berenices. Its velocity with respect to the cosmic microwave background is 6675 ± 18 km/s, which corresponds to a Hubble distance of 98.45 ± 6.90 Mpc (∼321 million light-years).[1] It was discovered by German-British astronomer William Herschel on 11 April 1785.[2]

NGC 5032 was used by Gérard de Vaucouleurs as a galaxy of morphological type (R′)SAB(rs)b in his atlas of galaxies.[2]

NGC 5032 is classified as a LINER galaxy, i.e. it has a type of nucleus that is defined by its spectral line emission which has weakly ionized or neutral atoms, while the spectral line emission from strongly ionized atoms is relatively weak.[1]

NGC 5032 forms a interacting galaxy pair with PGC 45940 (sometimes called NGC 5032B).[2] Erik Holmberg included the group in his catalog of double and multiple galaxies, with the designation Holm 513.[3] NGC 5032 is also on the outskirts of the Coma Cluster, identified as ComaFC 370.[4]
