Physical characteristics
The asteroid belongs to the V-type taxonomic class, having a spectrum similar to the large asteroid 4 Vesta. It is spinning with a rotation period of 10.9 days.[1]
Based on observations from the Pan-STARRS (Panoramic Survey Telescope and Rapid Response System) telescope network and observations from the Asteroid Terrestrial-impact Last Alert System (ATLAS), the asteroid's absolute magnitude was initially estimated to be 14.39 ± 0.20m (Vereš, P., et al. 2015),[2] and later, 14.40 ± 0.137m (Mahlke, M., et al. 2021).[3]
