Climenhaga is a member of the Flora family, one of the largest families of stony asteroids in the main belt. It orbits the Sun in the inner main-belt at a distance of 1.8–2.8 AU once every 3 years and 6 months (1,294 days). Its orbit has an eccentricity of 0.21 and an inclination of 5° with respect to the ecliptic.[1]
The asteroid's observation arc begins with its official discovery observation at Heidelberg, as no precoveries were taken, and no prior identifications were made.[7]
In July 2009, a rotational lightcurve of Climenhaga was obtained from photometric observations by an international collaboration led by Australian astronomer Julian Oey at Kingsgrove (E19) and Leura (E17) observatories. Lightcurve analysis gave a well-defined rotation period of 2.737485 hours with a brightness amplitude of 0.10 magnitude (U=3).[5]
Diameter and albedo
The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, a S-type asteroid and the family's largest member and namesake – and calculates a diameter of 7.82 kilometers with an absolute magnitude of 12.7.[3]
Satellite
During the photometric observation in July 2009, a minor-planet moon, designated S/2009 (3034) 1, was discovered orbiting Climenhaga with an orbital period of 18.954 hours. The discovery was not announced until 2013.[5] The satellite's orbit has an estimated semi-major axis of 19 kilometers.[4]
