2014 EC has only been observed on two nights for a period of less than 48 hours, with a remaining orbital uncertainty of 4 and 6 respectively.[1][2] It orbits the Sun at a distance of 0.7–2.2 AU once every 21 months (644 days). Its orbit has an eccentricity of 0.53 and an inclination of 1° with respect to the ecliptic.[1]
Based on a generic magnitude-to diameter conversion, 2014 EC measures 7 meters in diameter, for a measured absolute magnitude of 28.2 and an assumed albedo of 0.2, which is typical value for stony S-type asteroids.[3] Other sources estimated the body to be approximately 10 meters or 30 feet across.[4] It is too small for being a potentially hazardous asteroid, which require an absolute magnitude of 22.0 or less.[6]
