Photometric observations during 2003 showed a rotation period of 6.48 ± 0.01 hours with a brightness variation of 0.27 ± 0.03 in magnitude. An earlier study yielded results that are consistent with these estimates. Agathe is the lowest numbered asteroid to have an Earth-MOID as low as . On 23 August 2029 the asteroid will be  from Earth.
