NGC 4309 is a lenticular galaxy located about 55 million light-years away[3] in the constellation Virgo. The galaxy was discovered by astronomer Christian Peters in 1881[4] and is a member of the Virgo Cluster.[5][6]

NGC 4309 is classified as an AGN[7] and has undergone ram-pressure stripping.[8]

Globular clusters

Within a distance of 160,000 ly (50 kpc) from NGC 4309 exists a population of 162 globular clusters that surround the galaxy.[9]
