NGC 5713 is a peculiar, asymmetric galaxy in the constellation Virgo. Although classified as a spiral galaxy by most galaxy catalogs, NGC 5713 is very different from most normal spiral galaxies. While most spiral galaxies either have either two well-defined spiral arms or a filamentary spiral-like structure, this spiral galaxy has only one visible spiral arm in its disk.[2] This makes it a galaxy of the Magellanic type. Gravitational interactions with the nearby spiral galaxy NGC 5719[3] may be responsible for producing the disturbed, asymmetric structure including the single spiral arm.
NGC 5713 is at the center of a small group of spiral galaxies that also includes NGC 5691, NGC 5705, and NGC 5719.[2] It is a member of the NGC 5746 Group of galaxies, itself one of the Virgo III Groups strung out to the east of the Virgo Supercluster of galaxies.[4]
