5481 Kiuchi, provisional designation 1990 CH, is a bright
rotation period of 3.6 hours.[5]
Family and orbit
Kiuchi is a bright core member of the
Crimea–Nauchnij in 1970, extending the body's observation arc by 20 years prior to its official discovery observation at Kitami.[9]

In March 2008, a
Judit Györgyey Ries at McDonald Observatory
, Texas.
These photometric observations revealed, that Kiuchi is a synchronous binary asteroid with a minor-planet moon orbiting it every 20.90 hours based on mutual eclipsing and occultation events. The satellite's diameter is about a third of that of Kiuchi, which translates into 1.3 kilometers (secondary-to-primary mean-diameter ratio of 0.33±0.02).[4]
Primary
According to the surveys carried out by
PanSTARRS, Kiuchi is a bright V-type asteroid.[7] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.40 and calculates a diameter of 3.86 kilometers, using an absolute magnitude of 13.676 from Petr Pravec's revised WISE data.[5]
