2014 EC is a 10-meter sized, eccentric asteroid, classified as a near-Earth object of the Apollo group that passed within 48000 mi km 2 of Earth in early March 2014. This was six times closer to the Earth than the Moon. It was first observed on 5 March 2014, by the Catalina Sky Survey at Mount Lemmon Observatory in Arizona, United States. As of 2017, it has not since been observed.
Description
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. 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.
The asteroid has an Earth minimum orbital intersection distance of 0.0005 AU km on 3 which translates into less than 0.2 lunar distances.
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. Other sources estimated the body to be approximately 10 meters or 30 feet across. It is too small for being a potentially hazardous asteroid, which require an absolute magnitude of 22.0 or less.
