It was discovered by Irish engineer Bindon Stoney on April 26, 1851.[11] NGC 5774 belongs to a small group of galaxies, together with nearby NGC 5775 and IC 1070.[12] It has been classified as a "low surface brightness" (LSB) galaxy, but its central surface brightness is 5 times brighter than the brightest LSB galaxies.[12][14] It has a multiple spiral pattern with bright blue knotty structure all along the arms.[15] It is an extremely low star forming galaxy with five X-ray sources plus three ultraluminous X-ray source candidates.[1] Interaction with NGC 5775NGC 5774 is interacting with the nearby spiral galaxy NGC 5775 in the form of two connecting H I bridges through which the gas is travelling from NGC 5774 to NGC 5775.[12] Faint optical emission, as well as radio continuum emission, are also present along the bridges.[14] It is possible that star formation is occurring between the galaxies.[12] This system may be in the early stages of a merger.[14] See also
