Messier 83 or M83, also known as the Southern Pinwheel Galaxy and NGC 5236, is a barred spiral galaxy^[7] approximately 15 million light-years away in the constellation borders of Hydra and Centaurus. Nicolas-Louis de Lacaille discovered M83 on 17 February 1752 at the Cape of Good Hope.^[8] Charles Messier added it to his catalogue of nebulous objects (now known as the Messier Catalogue) in March 1781.^[8]

It is one of the closest and brightest barred spiral galaxies in the sky, and is visible with binoculars.^[9] It has an isophotal diameter at about 36.24 kiloparsecs (118,000 light-years). Its nickname of the Southern^[a] Pinwheel derives from its resemblance to the Pinwheel Galaxy (M101).
