NGC 5917 is a spiral galaxy located in the constellation of Libra. It was discovered by English astronomer John Herschel on 16 July 1835.[8] This galaxy is located at a distance of 90.4 ± 6.2 million light-years (27.73 ± 1.90 Mpc) from the Milky Way,[3] and is receding with a heliocentric radial velocity of 1,934.1 km/s.[4] It is interacting with the neighboring galaxy, PGC 54817, at an angular separation of 4.2′. Tidal tails extend from PGC 54817 to the halo of NGC 5917.[5]

A supernova was observed in NGC 5917, designated SN 1990Q. It was discovered on June 24, 1990 and reached magnitude 18.[9] This was identified as a type II supernova based on the spectrum.[10]
