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]
