Polyxena (minor planet designation: 595 Polyxena) is a minor planet orbiting the Sun. This main belt asteroid was discovered on 27 March 1906 by German astronomer August Kopff at the Heidelberg observatory. It was named after the youngest daughter of Priam and Hecuba, king and queen of Troy during the Trojan War.[3] 595 Polyxena is orbiting at a distance of 3.21 AU from the Sun, with an orbital eccentricity (ovalness) of 0.06 and a period of 5.75 yr (2,099.1 d). The orbital plane is inclined at an angle of 17.8° to the ecliptic.[2]
Light curves generated from photometric data indicate a sidereal rotation period of 11.794162±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]
