Hunnia is an assumed carbonaceous C-type asteroid,[4] in agreement with the overall spectral type of the Meliboea family.
[12]: 23 Between February and March 1998, a rotational lightcurve of Hunnia was obtained from photometric observations by Hungarian astronomers Krisztián Sárneczky, Gyula Szabó and László Kiss.
Lightcurve analysis gave a rotation period of 17.2 hours with a brightness amplitude of 0.34 magnitude (U=2).
