2014 SS349 is an extreme trans-Neptunian and scattered disc object from the outermost regions of the Solar System, approximately 134 kilometers in diameter.[3][4]
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, Johnston's Archive calculated a mean-diameter of 134 kilometers.[4]
