2014 EC
The term "2014 EC" likely refers to an asteroid or other small celestial body discovered in the year 2014, with "EC" being a designation assigned as part of the object's provisional naming convention. This designation is assigned by the Minor Planet Center (MPC), which is the official body responsible for the designation of minor planets (asteroids), comets, and natural satellites.
The full designation would typically be more complete, including a year and a string of letters and numbers detailing the specific order of discovery and observations. For example, the full designation might look something like "2014 EC1" or "2014 EC15," where the numbers indicate the order of discovery within that particular half-month of the year.
Without the full designation, it is impossible to determine the specific characteristics of "2014 EC," such as its size, orbit, composition, or potential threat to Earth. Astronomical databases like the JPL Small-Body Database or the MPC database would contain detailed information about the object once its orbit is well-determined and it receives a permanent number.
