It was discovered on 16 August 1971, by American astronomer James Gibson at the Yale–Columbia Southern Station of the Leoncito Astronomical Complex in Argentina, who named it after his wife Ursula ("Osita"). Orbit and classification The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun in the inner main-belt at a distance of 2.0–2.4 AU once every 3 years and 3 months (1,196 days). Its orbit has an eccentricity of 0.09 and an inclination of 4° with respect to the ecliptic. Osita was first identified as 1962 XQ at Goethe Link Observatory in 1962, extending the body's observation arc by 9 years prior to its official discovery observation. Physical characteristics PanSTARRSs large-scale survey also classified Osita as a rare AQ-type, having intermediate spectral characteristics of an A and Q type asteroid. Rotation period In February 2006, a rotational lightcurve of Osita was obtained from photometric observation by French amateur astronomer René Roy, giving a well-defined rotation period of 3.81880 hours with a brightness variation of 0.48 magnitude (U=3). Photometric observations in the R-band at the Palomar Transient Factory in October 2011, gave a concurring period of 3.8186 hours and an amplitude of 0.59 magnitude (U=2). A third period of 3.81880 hours was derived from a large international data-mining collaboration in February 2016 (U=n.a.). Diameter and albedo According to the surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Osita measures between 7.53 and 7.94 kilometers in diameter, and its surface has an albedo between 0.194 and 0.216. The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of this orbital family – and calculates a diameter of 7.14 kilometers with an absolute magnitude of 12.9. Naming This minor planet was named by the discoverer for his wife Ursula ("Osita" is the Spanish equivalent). She volunteered as an assistant and actively participated in the observations by measuring or reducing more than 150 positions of comets and minor planets. The official 1837 naming citation was published by the Minor Planet Center on 20 February 1976 (M.P.C. 3935). References 30em 2017-03-11 last obs.
