3034 Climenhaga/ˈklaɪmɪnheɪɡə/ is a stony Florianasteroid and synchronousbinary asteroid from the inner regions of theasteroid belt, approximately 7.8 kilometers in diameter. The asteroid was discovered on 24 September 1917 by German astronomerMax Wolf atHeidelberg Observatory in southwest Germany and assigned provisional designationA917 SE.[1] It was later named after Canadian astrophysicistJohn Climenhaga. Itsminor-planet moon has aperiod of nearly 19 hours.
Climenhaga is a member of theFlora family, one of the largest families of stony asteroids in the main belt. It orbits the Sun in theinner main-belt at a distance of 1.8–2.8 AU once every 3 years and 6 months (1,294 days). Its orbit has aneccentricity of 0.21 and aninclination of 5° with respect to theecliptic.[1]
The asteroid'sobservation arc begins with its official discovery observation at Heidelberg, as noprecoveries were taken, and no prior identifications were made.[7]
Climenhaga has been characterized as a commonS-type asteroid.[3]
In July 2009, a rotationallightcurve ofClimenhaga 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-definedrotation period of 2.737485 hours with a brightness amplitude of 0.10magnitude (U=3).[5]
TheCollaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from8 Flora, aS-type asteroid and the family's largest member and namesake – and calculates a diameter of 7.82 kilometers with anabsolute magnitude of 12.7.[3]
During the photometric observation in July 2009, aminor-planet moon was discovered orbitingClimenhaga with anorbital period of 18.954 hours. The discovery was not announced until 2013.[5] The satellite's orbit has an estimatedsemi-major axis of 19 kilometers.[4]
Thisminor planet was named in 1987 for Canadian John Leroy Climenhaga of theUniversity of Victoria, in honour of his work inastrophysics.[2] The approved naming citation was published by theMinor Planet Center on 16 December 1986 (M.P.C. 11441).[8]
