2661 Bydžovský

[2] Bydžovský orbits the Sun in the outer main-belt at a distance of 2.7–3.3 AU once every 5 years and 3 months (1,923 days).

[1] It was first identified as 1950 EE at Heidelberg Observatory in 1950, extending the body's observation arc by 32 years prior to its discovery.

Based on its absolute magnitude of 11.4, its diameter is estimated to measure 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] This minor planet was named in honour of mathematician Bohumil Bydžovský (1880–1969), chancellor of the Charles University in Prague.
