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. 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. 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). 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. 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 G69, California, in November 2011. It gave a well-defined rotation period of 5.78 0.01 hours with a brightness variation of 0.36 in magnitude (U=3). 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. Previous results by WISE/NEOWISE also gave a diameter of 6.03 and 8.4 kilometers. 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. 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". The official 1982 naming citation was published by the Minor Planet Center on 18 April 1977 (M.P.C. 4158). References 30em 2017-05-04 last obs.
