Peculiar Galaxy NGC 5713
27-Jun-2019
NGC 5713 (right) is a peculiar, asymmetric galaxy, interacting with NGC 5719 (left) in the constellation Virgo.
Although classified as a spiral galaxy by most galaxy catalogs, NGC 5713 galaxy 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. This makes it a galaxy of the Magellanic type. Gravitational interactions with the nearby spiral galaxy NGC 5719 may be responsible for producing the disturbed, asymmetric structure including the single spiral arm. Source: Wikipedia
