Overview

138127 (2000 EE14) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2000 EE14 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2000 EE14 orbits the sun every 197 days (0.54 years), coming as close as 0.31 AU and reaching as far as 1.01 AU from the sun. 2000 EE14 is about 0.8 kilometers in diameter, making it small in absolute terms, but larger than ~97% of asteroids, comparable in size to the Golden Gate Bridge.

The rotation of 2000 EE14 has been observed. It completes a rotation on its axis every 2.59 days.

Close Approaches

2000 EE14's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2000 EE14 has 39 close approaches predicted in the coming decades:
