NGC 716 is a largebarred spiral galaxy located in theconstellation Aries,[4] about 200 million light-years away from theMilky Way. Theluminosity class of NGC 716 is I and has a large HI line.[5] It also contains regions of ionized hydrogen. Many non-redshift measurements provide a distance of 54,023±8,169Mpc (~176 millionlight years), which is within the distances calculated using theredshift value.[6]
NGC 716 was discovered in 1886 by AmericanastronomerLewis Swift using a 40.64 cm (16 inch)optical telescope that used amirror as a light-gathering element. It was also observed by the French astronomerGuillaume Bigourdan on 1 January 1892 and was added to theIndex Catalog with the code IC 1743.
