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.
Interaction with NGC 5774
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.[5] Faint optical emission as well as radio continuum emission are also present along the bridges.[6] It is possible that star formation is occurring between the galaxies.[5]
This system may be in the early stages of a merger.[6]
