NGC 7466 is aspiral galaxy in theconstellation ofPegasus. Its velocity with respect to thecosmic microwave background is 7160 ± 25 km/s, which corresponds to aHubble distance of 105.60 ± 7.40Mpc (~344 millionlight-years).[1] It was discovered by French astronomerÉdouard Stephan on 20 September 1873.[2] It was independently rediscovered by the French astronomerGuillaume Bigourdan on 19 November 1895 and listed as IC 5281 in theIndex Catalogue.[2]
NGC 7466 is listed as aSeyfert 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 ofultraviolet emissions, and is thus listed in theMarkarian Galaxy Catalog as Mrk 1127.[1]
Onesupernova 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]
