Kilia /ˈkɪliə/ (minor planet designation: 470 Kilia) (1901 GJ) is a 27 km main-belt asteroid discovered on 21 April 1901 by Luigi Carnera at Heidelberg,[1] the 470th asteroid discovered. It was one of the 16 asteroid discoveries made by Carnera.
Photometric observations of this asteroid in 2021 were used to produce a light curve showing a rotation period of 297.655±0.012 h with a brightness amplitude of 0.40±0.02 in magnitude.[2]
