1825 Klare, provisional designation 1954 QH, is a stony asteroid from the middle region of the asteroid belt, that measures between 15 and 20 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 31 August 1954.[10]
The S-type asteroid orbits the Sun at a distance of 2.4–3.0 AU once every 4.38 years (1,601 days). Its orbit has an eccentricity of 0.12 and is tilted by 4 degrees to the plane of the ecliptic.[1] For a silicaceous asteroid, it has a rather low albedo of 0.10–0.17.[3][4]
The main-belt asteroid has been the subject of multiple light-curve studies, which delivered an exceptionally well-determined rotation period of 4.74 hours.[5][6][7][8] Measurements have also been used as the basis for generating a three-dimensional model of its shape.[9]
It was named after Gerhard Klare (born 1932), an observing astronomer at Heidelberg Observatory since 1960, whose fields of interest include minor planets.[2] He is also known for his numerous contributions in the yearbook series "Reviews in Modern Astronomy" of the Astronomische Gesellschaft.
