1982 Cline, provisional designation Template:Mp, is a stony asteroid from the inner regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered on 4 November 1975, by American astronomer Eleanor Helin at Palomar Observatory in California, and named after Edwin Lee Cline, inventor and friend of the discoverer.[1][2]
Classification and orbit
Cline is a stony S-type asteroid that orbits the Sun in the inner main-belt at a distance of 1.7–2.9 AU once every 3 years and 6 months (1,283 days). Its orbit has an eccentricity of 0.25 and an inclination of 7° with respect to the ecliptic.[3] As a main-belt asteroid with a perihelion of less than 1.74 AU, it is not far from being a Mars-crosser (1.67 AU).[3] The first precovery was taken at Johannesburg Observatory (Hartbeespoort, 076) in 1957, extending the asteroid's observation arc by 18 years prior to its discovery.[2]
Physical characteristics
The body's first and only rotational lightcurve of Cline was obtained by American astronomer James W. Birnsfield at the Via Capote Observatory Template:Obscode, California, in November 2011. It gave a well-defined rotation period of Template:Val hours with a brightness variation of 0.36 in magnitude (U=3Script error: No such module "Check for unknown parameters".).[4]
According to the survey carried out by the Japanese Akari satellite and the latest data from the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Cline measures 7.2 and 8.1 kilometers in diameter and its surface has an albedo of 0.194 of 0.34, respectively.[5][6] Previous results by WISE/NEOWISE also gave a diameter of 6.03 and 8.4 kilometers.[7][8] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 8.18 kilometers with an absolute magnitude of 12.8.[9]
Naming
This minor planet was named in memory of Edwin Lee Cline, a friend of the discoverer and a known inventor in the automotive field who "looked to space as the new frontier".[1] The official Template:MoMP was published by the Minor Planet Center on 18 April 1977 (M.P.C. 4158Script error: No such module "Check for unknown parameters".).[10]
