 The spectrum of "Hirayama" matches a C-type classification on the Tholen taxonomic scheme, but with a "broad absorption band that can be associated to a process of aqueous alteration".That is, the surface appears to show some form of water modification.This minor planet is named in honour of Japanese astronomer Kiyotsugu Hirayama (1874–1943), best known for his discovery that many asteroid orbits were more similar to one another than chance would allow, leading to the concept of asteroid families, now called Hirayama families.
