[2][3] It is considered a classical example of an object submitted to the Kozai effect, induced by an outer perturber, which in this case is the gas giant Jupiter.
[5] Kozai orbits the Sun in the inner main-belt at a distance of 1.5–2.2 AU once every 2 years and 6 months (912 days).
[1] On 10 January 2044, the asteroid will make a close approach to Mars, passing the Red Planet at a distance of 0.034 AU (5,090,000 km).
[1][6] With an absolute magnitude of 13.8, Kozai's diameter can be estimated to measure between 4 and 11 kilometers, for an assumed albedo in the range of 0.05–0.25.
[4] Since Kozai is a brighter S-type asteroid rather than a darker carbonaceous body, its diameter is on the lower end of NASA's generic conversion table, as the larger the body's diameter, the lower its albedo at a constant absolute magnitude.
