NGC 4694 is alenticular galaxy in the constellationVirgo. Its velocity with respect to thecosmic microwave background is 1481 ± 23 km/s, which corresponds to aHubble distance of 71.3 ± 5.1 Mly (21.85 ± 1.57 Mpc).[2] However, sixnon redshift measurements give a distance of 28.51 ± 7.23 Mly (8.742 ± 2.218 Mpc).[3] The galaxy was discovered byWilliam Herschel on March 15, 1784.[4]
According to theSIMBAD database, NGC 4694 has anActive Galaxy Nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[5]
According to A.M. Garcia, NGC 4694 is one of 127 galaxies in the M49 group (also known asLGG 292). This group includes 63 galaxies from theNew General Catalogue, including NGC 4382 (M85), NGC 4472 (M49),NGC 4516, NGC 4649 (M60) and 20 galaxies from theIndex Catalogue.[6]
