3169 Ostro, provisional designation 1981 LA, is a
Hungaria family asteroid from the innermost regions of the asteroid belt
, approximately 5 kilometers in diameter.
The asteroid was discovered on 4 June 1981, by American astronomer
Edward Bowell at Lowell's Anderson Mesa Station in Flagstaff, Arizona,[3] and named after planetary scientist Steven J. Ostro at JPL.[2]
Orbit and classification
Ostro is a member of the
Hungaria family, which form the innermost dense concentration of asteroids in the Solar System. It orbits the Sun at a distance of 1.8–2.0 AU once every 2 years and 7 months (950 days). Its orbit has an eccentricity of 0.07 and an inclination of 25° with respect to the ecliptic.[1]
Physical characteristics
In the
SMASS taxonomy, Ostro is classified as a TS-type and Xe-type asteroid, respectively.[1] It has also been characterized as an E-type asteroid.[4]
According to the survey carried out by NASA's
albedo of 0.960.[5] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.5152 and a diameter of 5.27 kilometers with an absolute magnitude of 12.73.[4]
