NGC 5775 is a spiral galaxy, a member of the Virgo 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 the NGC 5775 Group of galaxies, itself one of the Virgo III Groups strung out to the east of the Virgo Supercluster of galaxies.^[5]

One supernova has been observed in NGC 5775: SN 1996ae (type IIn, mag. 16.5).^[6]

Interaction with NGC 5774 edit

NGC 5775 is interacting with the nearby galaxy NGC 5774 in the form of two connecting H I bridges through which the gas is travelling from NGC 5774 to NGC 5775.^[7] Faint optical emission as well as radio continuum emission are also present along the bridges.^[8] It is possible that star formation is occurring between the galaxies.^[7]

This system may be in the early stages of a merger.^[8]
