NGC 4305 is a dwarf spiral galaxy[2] located about 100 million light-years away[3] in the constellation Virgo.

[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] 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).
