5653 Camarillo, provisional designation 1992 WD5, is a stony asteroid classified as near-Earth object and Amor asteroid, about 1.5 kilometers in diameter. It was discovered by American astronomers Eleanor Helin and Kenneth J. Lawrence at the U.S. Palomar Observatory on 21 November 1992.[11]
The S-type asteroid orbits the Sun at a distance of 1.2–2.3 AU once every 2 years and 5 months (878 days). Its orbit shows a high eccentricity of 0.30 and an inclination of 7 degrees from the plane of the ecliptic. The near-Earth asteroid has an Earth minimum orbit intersection distance, MOID, of Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value)..[1]
Between 1995 and 2015, several photometric light-curve analysis gave it a well-defined rotation period of 4.834 hours with a brightness amplitude in the range of 0.4–0.85 in magnitude.[7][lower-alpha 1][8][9][10] According to the surveys carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid has an albedo between 0.21 and 0.25 with a corresponding diameter of 1.53 to 1.57 kilometers.[3][4][5]
The minor planet was named after the Camarillo Observatory (670), located in the Californian town of Camarillo, which was named after Adolfo Camarillo (1864–1958), a prominent local rancher. The first discoverer is a former town resident.[2]
