It is a member of the NGC 4699 Group 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.[1]

In 2012, a possible supernova, SN 2012au was detected in NGC 4790.[2] This supernova later produced evidence of a pulsar wind nebula which appears to be expanding outward at approximately 2300 km/s. [3]
