rotation period
of 10.7 hours and measures approximately 15 kilometers (9.3 miles) in diameter.

Classification and orbit

Bok orbits the Sun in the central main-belt at a distance of 2.4–2.9 AU once every 4 years and 3 months (1,550 days). Its orbit has an eccentricity of 0.10 and an inclination of 9° with respect to the ecliptic.[1] The first observation was taken at the Argentinian La Plata Astronomical Observatory in 1950, extending the asteroid's observation arc by 25 years prior to its discovery.[7]

. Both astronomers studied the structure of the southern Milky Way and fostered astronomy in the Southern Hemisphere.

Bok was the first numbered discovery made with the Stewart Observatory's 90-inch

M.P.C. 4158).[8]

Physical characteristics

Bok has been characterized as a C-type asteroid.[4]

In October 2014, the first rotational

The Italian astronomer also calculated an albedo of 0.06 for its surface and a diameter of 15±3 kilometers, in agreement with the survey carried out by the

NEOWISE mission of NASA's Wide-field Infrared Survey Explorer which gave a diameter of 15.7 kilometers and an albedo of 0.034.[5]

The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.10, a compromise value between the

semi-major axis between 2.6 and 2.7 AU, and consequently calculates a much smaller diameter of 10.08 kilometers using an absolute magnitude of 13.1.[3]
