[8] Počátky is a stony S-type asteroid, that orbits the Sun in the middle main-belt at a distance of 2.4–2.9 AU once every 4 years and 3 months (1,559 days).
[1] A first precovery was taken at ESO's La Silla Observatory in 1991, extending the asteroid's observation arc by 6 years prior to its discovery.
[8] Two rotational lightcurves for this asteroid were obtained from photometric observations made at the U.S Palomar Transient Factory, California, in August 2010 and February 2012.
[6] According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, Počátky measures 4.0 kilometers in diameter and its surface has an albedo of 0.23,[4][5] while the Collaborative Asteroid Lightcurve Link (CALL) assumes an untypically low albedo for stony asteroids of 0.10, and thus calculates a larger diameter of 4.9 kilometers.
[3] This minor planet was named after the south Bohemian town of Počátky, Czech Republic.
