NGC 3052 is anintermediate spiral galaxy in theconstellation ofHydra. Its velocity concerning thecosmic microwave background is 4122 ± 24 km/s, which corresponds to aHubble distance of 60.79 ± 4.27Mpc (~198 millionlight-years).[1] However, 19nonredshift measurements give a much closer distance of 42.563 ± 6.434 Mpc (139 million light-years).[2] The galaxy was discovered by German-British astronomerWilliam Herschel on 7 February 1785.[3]
TheSIMBAD database lists NGC 3052 as aSeyfert I Galaxy, i.e. it has aquasar-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]
Onesupernova has been observed in NGC 3052: SN 2024chx (type II, mag. 18.2315) was discovered by theZwicky Transient Facility on 12 February 2024.[5]
The galaxy NGC 3052 is part of the NGC 3091group (also known asLGG 186), which includes at least 5 other galaxies:NGC 3091,NGC 3124, PGC 28926, MCG -3-26-6, and ESO 566–19.[6]
