NGC 2300 is alenticular galaxy in the constellationCepheus.[2] Its velocity with respect to thecosmic microwave background is 1876 ± 7 km/s, which corresponds to aHubble distance of 90.2 ± 6.3 Mly (27.67 ± 1.94 Mpc).[2] However, 11non redshift measurements give a distance of 131.98 ± 21.75 Mly (40.464 ± 6.668 Mpc).[5] The galaxy was discovered in 1871 by French astronomerAlphonse Borrelly using an 18 cm telescope.[4]
Together withNGC 2276, they form the 114th object inHalton Arp'sAtlas of Peculiar Galaxies.[6]
According to theSIMBAD database, NGC 2300 is anActive 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.[1]
Onesupernova has been observed in NGC 2300: SN 2024uai (type Ia-91bg-like, mag. 16.58).[7]
