Classification and orbit
Dvořák is a
Mars-crossing asteroid, as it crosses the orbit of Mars at 1.666 AU. It orbits the Sun at a distance of 1.6–3.0 AU once every 3 years and 6 months (1,283 days). Its orbit has an eccentricity of 0.31 and an inclination of 21° with respect to the ecliptic.[1] The body's observation arc begins with its official discovery observation at Bergedorf in 1974.[3]
