31824 Elatus (

outer Solar System, approximately 48 kilometers (30 miles) in diameter. It was discovered on 29 October 1999, by astronomers of the Catalina Sky Survey at Mount Lemmon Observatory in Arizona, United States.[5] The minor planet was named after Elatus, a centaur from Greek mythology.[3]

Orbit and classification

Elatus orbits the Sun at a distance of 7.3–16.3 AU once every 40 years and 7 months (14,826 days). Its orbit has an eccentricity of 0.38 and an inclination of 5° with respect to the ecliptic.[1]

The body's observation arc begins with a precovery taken by the Sloan Digital Sky Survey at Apache Point Observatory in September 1998, thirteen months prior to its official discovery observation.[5]
