NGC 4305 is a dwarf spiral galaxy [2] located about 100 million light-years away [3] in the constellation Virgo. The galaxy was discovered by astronomer John Herschel on May 2, 1829. [4] Although considered to be a member of the Virgo Cluster, [2] [5] its high radial velocity and blue luminosity suggest it is in fact a background galaxy. [6] The galaxy has a nearby major companion; NGC 4306. [6]

NGC 4305 exhibits well-defined, smooth spiral arms which terminate well outside its central bulge. [7] This spiral structure appears to have been induced by a tidal interaction with NGC 4306. [8] [9] Such a tidal interaction would also explain its deficiency in neutral hydrogen gas (HI). [6]
