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). However, 19 non redshift measurements give a much closer distance of 42.563 ± 6.434 Mpc (139 million light-years). The galaxy was discovered by German-British astronomer William Herschel on 7 February 1785.

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.

One supernova has been observed in NGC 3052: SN 2024chx (type II, mag. 18.2315) was discovered by the Zwicky Transient Facility on 12 February 2024.

NGC 3091 Group

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.
