**NGC 5260** is a [barred spiral galaxy](/source/Barred_spiral_galaxy) in the [constellation](/source/Constellation) of [Hydra](/source/Hydra_(constellation)). Its velocity with respect to the [cosmic microwave background](/source/Cosmic_microwave_background) is 6789 ± 21 km/s, which corresponds to a [Hubble distance](/source/Hubble's_law) of 100.13 ± 7.02 [Mpc](/source/Megaparsec) (~327 million [light-years](/source/Light-years)).[1] It was discovered by [American](/source/United_States) astronomer [Lewis Swift](/source/Lewis_Swift) on 6 April [1885](/source/1885).[2]

According to the [SIMBAD](/source/SIMBAD) database, NGC 5260 is a [Seyfert](/source/Seyfert_galaxy) II galaxy, i.e. it has a quasar-like nuclei with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.[3]

NGC 5260 forms a physical pair with galaxy [ESO 509-93](https://en.wikipedia.org/w/index.php?title=ESO_509-93&action=edit&redlink=1) [[d](https://www.wikidata.org/wiki/Q91558178)], collectively named RR 254, with an optical separation of 241″ between them.[4]

## Supernovae

Two [supernovae](/source/Supernova) have been observed in NGC 5260:

- **SN 2022jkx** ([Type Ib](/source/Type_Ib_and_Ic_supernovae), mag. 18.819) was discovered by [ATLAS](/source/Asteroid_Terrestrial-impact_Last_Alert_System) on 3 May 2022.[5]

- **SN 2023dtd** ([Type II](/source/Type_II_supernova), mag. 18.516) was discovered by ATLAS on 20 March 2023.[6]
