NGC 5957 is a spiral galaxy located in the constellation Serpens. It lies at a distance of about 100 million light years from Earth based on redshift-independent methods, which, given its apparent dimensions, means that NGC 5957 is about 75,000 light years across.[1] It was discovered by Heinrich d'Arrest on April 29, 1865.[3]

NGC 5957 has a bar which is 0.96 arcminutes across. At the end of the bar lies an inner ring with a diameter of 0.94 arcminutes.[4] From the ring emerge multiple spiral arms[5] which form an outer ring with a diameter of 2.38 arcminutes.[4] The nucleus of the galaxy has been found to be active and has been identified as a LINER. The nucleus emits H-alpha that can't be resolved.[6]

One supernova has been discovered in NGC 5957, SN 2025fvw. It was discovered by Kōichi Itagaki on 26 March 2025 at an apparent magnitude of 17.4. It was identified as a type Ia supernova.[7]

NGC 5957 forms a pair with NGC 5956. A. M. Garcia considers NGC 5970 a member of the group, naming it LGG 401.[8] Other nearby galaxies include NGC 5953, NGC 5954, and NGC 5962.[9]
