NGC 4790 explained

NGC 4790 is a barred spiral galaxy located in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 1679 ± 24km/s, which corresponds to a Hubble distance of NaNMpc. In addition, six non-redshift measurements give a distance of NaNMpc.^[2] It was discovered on 25 March 1786 by German-British astronomer William Herschel.^[3]

NGC 4790 is a member of the NGC 4699 Group (also known as LGG 307) of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster.^{[4] [5]}

One supernova has been observed in NGC 4790. SN 2012au (typeIb, mag. 13.8) was discovered by the Catalina Sky Survey on 14 March 2012.^{[6] [7]} This supernova later produced evidence of a pulsar wind nebula which appears to be expanding outward at approximately 2300 km/s. ^[8]
