NGC 2523 is a barred spiral galaxy located around 168 million light-years away in the constellation Camelopardalis.[1] NGC 2523 was discovered on 7 September 1885 by the American astronomer Edward Swift, and is approximately 120,000 light-years across.[1][2][3] NGC 2523 does not have much star formation, and it does not have an active galactic nucleus.[2][4]
NGC 2523 is one of several galaxies chosen by Halton Arp as an example of a spiral galaxy that has a separation of one of its arms. It is listed in Arp's Atlas of Peculiar Galaxies as Arp 9.[5]
