NCG 5204 is a Magellanic spiral galaxy located about 14.5 million light-years away from Earth[note 1] in the constellation of Ursa Major and is a member of the M101 Group of galaxies.[4][5] It has a galaxy morphological classification of SA(s)m and is highly irregular, with only the barest indication of any spiral arm structure.[3] The galaxy's most prominent feature is an extremely powerful X-ray source designated NGC 5204 X-1. This has resulted in the galaxy being the target of several studies due to the strength of the source and its relative proximity to Earth.[6][clarification needed]
