NGC 4318 is a small lenticular galaxy[3] located about 72 million light-years away[5] in the constellation Virgo. It was discovered by astronomer John Herschel on January 18, 1828.[6] NGC 4318 is a member of the Virgo W′ group,[2][7][8][9] a group of galaxies in the background of the Virgo Cluster[2] that is centered on the giant elliptical galaxy NGC 4365.[9]
