2146 Stentor
2146 Stentor is a Jupiter trojan from the Greek camp, approximately in diameter. It was discovered on 24 October 1976, by Danish astronomer Richard Martin West at the ESO's La Silla Observatory in Chile. The dark Jovian asteroid has a rotation period of 16.4 hours and belongs to the 100 largest Jupiter trojans. It was named after Stentor from Greek mythology, a Herald of the Greeks during the Trojan War. Orbit and classification Stentor is a Jovian asteroid orbiting in the leading Greek camp at Jupiter's Lagrangian point, 60° ahead of the gas giant's orbit in a 1:1 resonance . It is a non-family asteroid in the Jovian background population. It orbits the Sun at a distance of 4.7–5.7 AU once every 11 years and 10 months (4,327 days; semi-major axis of 5.2 AU). Its orbit has an eccentricity of 0.10 and an inclination of 39° with respect to the ecliptic. The body's observation arc begins with its official discovery observation at La Silla in October 1976. Physical characteristics Stentor is an assumed C-type asteroid. Rotation period In June 2016, a rotational lightcurve of Stentor was obtained from photometric observations by Brian Warner at the Center for Solar System Studies
