NGC 5253 is an irregular galaxy in the constellation Centaurus. It was discovered by John Frederick William Herschel on 15 March 1787.[4]

Galaxy group information[edit]

NGC 5253 is located within the M83 Subgroup of the Centaurus A/M83 Group, a relatively nearby galaxy group that includes the radio galaxy Centaurus A and the spiral galaxy M83 (the Southern Pinwheel Galaxy).

NGC 5253 is considered a dwarf starburst galaxy.[5] Supernova 1972E, the second-brightest supernova visible from Earth (peak visual magnitude of 8.5, fainter only than SN 1987A) in the 20th Century, occurred in this galaxy.[6][7] Another supernova, SN 1895b, also has been recorded in the galaxy.[8]
