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]
