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
NGC 5253 is located within the M83 Subgroup of the Centaurus A/M83 Group, a relatively nearby group of galaxies 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 brightest supernova visible from Earth (visual magnitude of 8.5) in the 20th century after 1987A, occurred in this galaxy.[6][7]
