2661 Bydžovský, provisional designation 1982 FC1, is an asteroid from the outer region of the asteroid belt, roughly 22 kilometers in diameter. It was discovered on 23 March 1982, by Czech female astronomer Zdeňka Vávrová at the South Bohemian Kleť Observatory in the Czech Republic.[4]
The asteroid orbits the Sun at a distance of 2.7–3.3 AU once every 5 years and 3 months (1,923 days). Its orbit is tilted by 10 degrees to the plane of the ecliptic and shows an eccentricity of 0.09.[1] Little is known about the asteroids size, composition, albedo and rotation, despite having a well-observed orbit with the lowest possible uncertainty – a condition code of 0 – and an observation arc, that spans over a period of more than 60 years.[1]
Based on its absolute magnitude of 11.4, its diameter could be anywhere between 13 and 32 kilometers, assuming an albedo in the range of 0.05 to 0.25.[3] Since most asteroids in the outer main-belt are of a carbonaceous rather than of a silicaceous composition, with low albedos, typically closer to 0.05 than to 0.25, the asteroid's diameter might be on the upper end of NASA's published conversion table, as the lower the reflectivity (albedo), the larger the body's diameter for a given absolute magnitude.[3]
The minor planet was named in honour of Academician Bohumil Bydžovský (1880–1969), chancellor of the Charles University in Prague and professor of mathematics. He was born in southern Bohemia and became the most eminent citizen of the Czech town Veselí on the Lužnice river, after which the minor planets 2321 Lužnice and 2599 Veselí were named, respectively.[2][5][6]
