Encyclopedic overview

NGC 2300 is a lenticular galaxy in the constellation Cepheus. Its velocity with respect to the cosmic microwave background is 1876 ± 7 km/s, which corresponds to a Hubble distance of 90.2 ± 6.3 Mly (27.67 ± 1.94 Mpc). However, 11 non redshift measurements give a distance of 131.98 ± 21.75 Mly (40.464 ± 6.668 Mpc). The galaxy was discovered in 1871 by French astronomer Alphonse Borrelly using an 18 cm telescope.

NGC 2300 may be the closest discovered giant radio galaxy (GRG), it has large radio lobes that stretch roughly 3.5 million light years across. The radio lobes have an apparent size of 132 arcmin, the largest of any giant radio galaxy. However, the radio lobes host was not identified with certainty and they may be hosted by NGC 2276, but this is unlikely because it is a spiral galaxy.
