[2] The asteroid orbits the Sun in the inner main-belt at a distance of 1.8–2.6 AU once every 3 years and 4 months (1,222 days).
[3] Based on its absolute magnitude of 13.4, it has an estimated diameter between 5 and 13 kilometers, assuming an albedo in the range of 0.05 to 0.25.
[4] Since most asteroids in the inner main-belt are of a silicaceous rather than of a carbonaceous composition, with higheralbedos, typically around 0.20, the asteroid's diameter might be on the lower end of NASA's published conversion table, as the higher the reflectivity (albedo), the smaller the body's diameter at a constant intrinsic brightness (absolute magnitude).
He succeeded Frost as Yerkes director in 1932 and was the major force responsible for the establishment of the Texan McDonald Observatory in 1933.
Managing editor of the Astrophysical Journal from 1932 to 1947 and became head of the astronomy department of the University of California in Berkeley in 1950.
