Orbit and classificationEdit
Victor Jara is a non-family asteroid of the main belt's background population. It orbits the Sun in the inner main-belt at a distance of 1.8–2.5 AU once every 3 years and 2 months (1,168 days; semi-major axis of 2.17 AU). Its orbit has an eccentricity of 0.17 and an inclination of 3° with respect to the ecliptic.
Diameter and albedoEdit
Víctor Jara toured the Soviet Union in the 1960s and praised its culture, its scientific achievements and the friendliness of its working people. He was tortured and murdered shortly after the 1973 Chilean coup d'état led by Army Commander-in-Chief Augusto Pinochet, that ended the democratically elected government of the socialist Salvador Allende Gossens.
