This is the brightest member of the so called NGC5084-Galaxy-Group (=LGG 345),situated at the end of a southwards extending filament of the Virgo-II-Galaxy-Cluster.Other members of this group are NGC5087,NGC5134,PGC46889,PGC46574,PGC46489 (on the picture right of NGC5084) and many others.
Measuring apparently 9,3′ × 1,7′ with a brightness of 10th magnitude,this galaxy is in reality one of the most massive ones in the Virgo-Supercluster.Slighty warped,it is classified as Hubble-type S0 and its real distance measures about 71mio light-years.
NGC5084 was first observed by William Herschel in 1785.
