Classification and orbit

Malbil

The body's observation arc begins with its first used observation at the discovering observatory in 1986, or 4 years after its official discovery observation.^[6]

Physical characteristics

As of 2017, Malbil{{'}}s effective size, its composition and albedo, as well as its rotation period and shape remain unknown.^[11] Based on a magnitude-to-diameter conversion, its generic diameter is between 5 and 12 kilometer for an absolute magnitude of 13.4, and an assumed albedo in the range of 0.05 to 0.25.^[4] Since asteroids in the inner main-belt are typically of stony rather than carbonaceous composition, with albedos of 0.20 or higher, Malbil{{'}}s diameter can be estimate to measure around 6.3 kilometers, as the higher its albedo (reflectivity), the lower the body's diameter at a constant absolute magnitude (brightness).^[4]

Naming

This minor planet was named after American fortepianist and musicologist Malcolm Bilson (born 1935), who gave a recital at the "Asteroids, Comets, Meteors" conference at Cornell University in New York.^[2] The approved naming citation was published by the Minor Planet Center on 28 July 1999 ({{small|M.P.C. 35485}}).^[15]

It was discovered on 30 January 1982, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station in Arizona, United States.^[6] It is named for pianist Malcolm Bilson.^[2] Classification and orbit Malbil is not a member of any known asteroid family. It orbits the Sun in the inner main-belt at a distance of 2.1–2.8 AU once every 3 years and 10 months (1,401 days). Its orbit has an eccentricity of 0.15 and an inclination of 7° with respect to the ecliptic.
