NGC 2300 is a lenticular galaxy in the constellation Cepheus.[4] Its velocity with respect to the cosmic microwave background is 1876 ± 7km/s, which corresponds to a Hubble distance of NaNMpc. However, 11 non redshift measurements give a distance of NaNabbr=onNaNabbr=on.[5] The galaxy was discovered in 1871 by French astronomer Alphonse Borrelly using an 18 cm telescope.[3]
Together with NGC 2276, they form the 114th object in Halton Arp's Atlas of Peculiar Galaxies.[6]
According to the SIMBAD database, NGC 2300 is an Active Galaxy Nucleus Candidate, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.
One supernova has been observed in NGC 2300: SN2024uai (typeIa-91bg-like, mag. 16.58).[7]
