Pravec (2012): rotation period of 500 hours with a brightness amplitude of 0.6 magnitude. CALL assigned a quality-code Q of 2 to the measurement, which means, that the result is based on less than full coverage, and that the period may be wrong by 30 percent or so. Summary figures for (6498) Ko at Collaborative Asteroid Lightcurve Link (CALL) and Pravec, P.; Wolf, M.; Sarounova, L. (2012)
