NGC 5988 is a large spiral galaxy in the constellation of Serpens. Its velocity with respect to the cosmic microwave background is 10697 ± 10 km/s, which corresponds to a Hubble distance of 514.6 ± 36.0 Mly (157.78 ± 11.05 Mpc).[1] However, one non-redshift measurement gives a much larger distance of 668.62 Mly (205.000 Mpc).[2] It was discovered by American astronomer Lewis Swift on 17 April 1887.[3]

NGC 5988 is 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.[4]

One supernova has been observed in NGC 5988: SN 2023hbv (type II, mag 19.278) was discovered by ATLAS on 29 April 2023.[5]
