2014 EC is a 10-meter sized, eccentric asteroid, classified as near-Earth object of the Apollo group that passed within Шаблон:Convert of Earth in early March 2014. This was six times closer to the Earth than the Moon.[1][2] 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.[3]

Description

Шаблон:Mp 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.[4][3] 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.[4]

The asteroid has an Earth minimum orbital intersection distance of Шаблон:Convert which translates into less than 0.2 lunar distances.[4]

Based on a generic magnitude-to diameter conversion, Шаблон:Mp 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.[5] Other sources estimated the body to be approximately 10 meters or 30 feet across.[1] It is too small for being a potentially hazardous asteroid, which require an absolute magnitude of 22.0 or less.[6]
