NGC 7466

NGC 7466 is a spiral galaxy in the constellation of Pegasus. Its velocity with respect to the cosmic microwave background is 7160 ± 25 km/s, which corresponds to a Hubble distance of 105.60 ± 7.40 Mpc (~344 million light-years).^[1] It was discovered by French astronomer Édouard Stephan on 20 September 1873.^[2] It was independently rediscovered by the French astronomer Guillaume Bigourdan on 19 November 1895 and listed as IC 5281 in the Index Catalogue.^[2]

NGC 7466 is listed as a Seyfert II Galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.^[1]

NGC 7466 is a galaxy with a nucleus that has excessive amounts of ultraviolet emissions, and is thus listed in the Markarian Galaxy Catalog as Mrk 1127.^[1]

One supernova has been observed in NGC 7466: SN 2023uu (Type Ia, mag. 20.1) was discovered by The Young Supernova Experiment (YSE) on 15 January 2023.^[3]
