    Description

    2014 SS349 was first observed on 22 September 2014, by astronomers at the Cerro Tololo Observatory near La Serena, Chile. [1]

    It orbits the Sun at a distance of 45.4–241.5  AU once every 1718 years and 7 months (627,720 days). Its orbit has an eccentricity of 0.68 and an inclination of 48° with respect to the ecliptic. [3]

    Based on an absolute magnitude of approximately 7.6 and an assumed albedo of 0.09, the Johnston's Archive calculated a mean-diameter of 134 kilometers. [4]
