595 Polyxena is aminor planet orbiting theSun. Thismain belt asteroid was discovered on 27 March 1906 by German astronomerAugust Kopff at theHeidelberg observatory. It was named after the youngest daughter ofPriam andHecuba, king and queen ofTroy during theTrojan War.[3] 595 Polyxena is orbiting at a distance of3.21 AU from the Sun, with anorbital eccentricity (ovalness) of 0.06 and aperiod of 5.75 yr (2,099.1 d). Theorbital plane isinclined at an angle of 17.8° to theecliptic.[2]
Light curves generated fromphotometric data indicate a siderealrotation period of11.794162±0.000023 h. Preliminary shape models of the asteroid suggest there's a flat region at the southern pole, perhaps indicating a concave area or an impact crater.[4]
