Orbit and classification
Čapek is a background asteroid, not associated to any known asteroid family. It orbits the Sun in the inner part of the central main-belt near the 3:1 resonance with Jupiter at a distance of 1.9–3.2 AU once every 4 years and 1 month (1,480 days). Its orbit has an eccentricity of 0.27 and an inclination of 8° with respect to the ecliptic.[1]
The asteroid was first identified as 1957 TK at
Crimea–Nauchnij, eleven days prior to its official discovery observation at Bergedorf.[4]
