32532 Thereus (

outer Solar System, approximately 80 kilometers (50 miles) in diameter. It was discovered on 9 August 2001, by astronomers of the Near-Earth Asteroid Tracking program at the Palomar Observatory in California, United States.[5] This minor planet was named for the phrase thēreios bia 'beastly strength', used to describe centaurs in Greek mythology.[2][3]

Orbit and classification

Thereus orbits the Sun at a distance of 8.5–12.7 AU once every 34 years and 8 months (12,676 days). Its orbit has an eccentricity of 0.20 and an inclination of 20° with respect to the ecliptic.[1]

The body's

Diameter and albedo

According to observations made by the

albedo between 0.059 and 0.0975.[6][7][8]

The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous minor planets of 0.057 and derives a diameter of 77.19 kilometers based on an absolute magnitude of 9.29.[4]
