    1982 Cline, provisional designation 1975 VA, is a stony asteroid from the inner regions of the asteroid belt, about 7 kilometers in diameter. It was discovered by American female astronomer Eleanor Helin at the U.S. Palomar Observatory in California, on 4 November 1975 .[8]

    The S-type asteroid orbits the Sun at a distance of 1.7–2.9 AU once every 3 years and 6 months (1,283 days). Its orbit is tilted by 7 degrees to the plane of the ecliptic and shows an eccentricity of 0.25. It has a rotation period of 5.8 hours[7] and a high albedo in the range of 0.24 to 0.37, according to the surveys carried out by the Japanese Akari satellite and the U.S. Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission.[4][5][6] The Collaborative Asteroid Lightcurve Link assumes a somewhat more moderate albedo of 0.20 for the stony body.[3]

    The asteroid was named by the discoverer to honor the memory of a friend, Edwin Lee Cline, who was a distinguished inventor in the automotive field who looked to space as the new frontier.[2]
