NGC 5775 is a spiral galaxy, a member of theVirgo Cluster, that lies at a distance of about 70 million light-years. Although the spiral is tilted away from us, with only a thin sliver in view, such a perspective can be advantageous for astronomers. For instance, astronomers have previously used the high inclination of this spiral to study the properties of the halo of hot gas[4] that is visible when the galaxy is observed at X-ray wavelengths. It is a member of theNGC 5775 Group of galaxies, itself one of theVirgo III Groups strung out to the east of theVirgo Supercluster of galaxies.[5]
Onesupernova has been observed in NGC 5775: SN 1996ae (Type IIn, mag. 16.5) was discovered by A. Vagnozzi, G. Piermarini, and V. Russo on 21 May 1996.[6][7]
NGC 5775 is interacting with the nearby galaxyNGC 5774 in the form of two connecting H I bridges through which the gas is travelling from NGC 5774 to NGC 5775.[8]Faint optical emission as well as radio continuum emission are also present along the bridges.[9] It is possible that star formation is occurring between the galaxies.[8]
This system may be in the early stages of amerger.[9]
