NGC 4492 is a
Arnold Schwassmann on January 23, 1900, and was listed as IC 3438.[6] NGC 4492 lies in the direction of the Virgo Cluster. However, it is not considered to be a member of that cluster.[7]
Physical characteristics
NGC 4492 has a relatively large
Interstellar dust.[8]
Virgo Cluster membership
NGC 4492 is listed in the Virgo Cluster Catalog as VCC 1330.[8] However, distance estimates to the galaxy place it at a location far outside of the cluster's center.[2][7] Also, its radial velocity indicates that NGC 4492 is not gravitationally bound to the Virgo Cluster but is expanding away from it. Therefore, NGC 4492 is not a member of the Virgo Cluster but rather a background galaxy.[7]
