637 Chrysothemis is a Themistian asteroid,[citation needed] which means it is a member of the Themis asteroid family.
In 2025, a photometric study of this minor planet was used to produce a light curve showing a rotation period of 42.93±0.01 hours with a brightness variation of 0.31±0.02 in magnitude. The light curve is bimodal and asymmetric.[3]
