2285 Ron Helin, provisional designation Шаблон:Mp, is a stony Florian asteroid from the inner region of the asteroid belt, approximately 4 kilometers in diameter. It was discovered on 27 August 1976, by American astronomer Schelte Bus at Palomar Observatory in San Diego County, California.[1]
Orbit and characterization
Ron Helin is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun in the inner main-belt at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,208 days). Its orbit has an eccentricity of 0.21 and an inclination of 5° with respect to the ecliptic. Its rotation period is 12 hours.[2]
Naming
This minor planet was named in honor of Ronald Helin, husband of American astronomer Eleanor Helin (1932–2009), in appreciation of his support of the Palomar Planet-Crossing Asteroid Survey (PCAS).[3] The approved naming citation was published by the Minor Planet Center on 11 December 1981 (Шаблон:Small).[4]
