Galaxy in the constellation Hydra
From Wikipedia, the free encyclopedia
NGC 5260 is a barred spiral galaxy in the constellation of Hydra. Its velocity with respect to the cosmic microwave background is 6789 ± 21 km/s, which corresponds to a Hubble distance of 100.13 ± 7.02 Mpc (~327 million light-years).[1] It was discovered by American astronomer Lewis Swift on 6 April 1885.[2]

According to the SIMBAD database, NGC 5260 is a Seyfert 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, collectively named RR 254, with an optical separation of 241″ between them.[4]
