NGC 3052 is an intermediate spiral galaxy in the constellation of Hydra. Its velocity with respect to the cosmic microwave background is 4122 ± 24 km/s, which corresponds to a Hubble distance of 60.79 ± 4.27 Mpc (∼198 million light-years).[1] However, 19 non redshift measurements give a distance of 42.563 ± 6.434 Mpc (139 million light-years).[2] The galaxy was discovered by German-British astronomer William Herschel on 7 February 1785.[3]
The SIMBAD database lists NGC 3052 as a Seyfert I 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.[4]
One supernova has been observed in NGC 3052: SN 2024chx (type II, mag. 18.2).[5]
The galaxy NGC 3052 is part of the NGC 3091 group (also known as LGG 186), which includes at least 5 other galaxies: NGC 3091, NGC 3124, PGC 28926, MCG -3-26-6, and ESO 566–19.[6]
