2014 EZ51 is a trans-Neptunian object and possible dwarf planet in the scattered disc, approximately 700 kilometers in diameter. It was first observed on 12 March 2014, by the Pan-STARRS 1 survey at Haleakala Observatory, Hawaii, United States.[2]
This minor planet orbits the Sun at a distance of 40.7–64.2 AU once every 379 years and 10 months (138,724 days). Its orbit has an eccentricity of 0.22 and an inclination of 10° with respect to the ecliptic.[1]
