Historical Identification: Per Dreyer, NGC 4456 (= GC 3007 = JH 3394, 1860 RA 12 21 43, NPD 119 19.7) is "most extremely faint, very small, 13th magnitude star attached". The position precesses to RA 12 29 05.1, Dec -30 06 11, but there is nothing there.

NGC 4456 is a Spiral Galaxy in the Hydra constellation. NGC 4456 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its B magnitude of 14.08, NGC 4456 is visible with the help of a telescope having an aperture of 14 inches (350mm) or more.
