Overview

5693 (1993 EA) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1993 EA as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

1993 EA orbits the sun every 523 days (1.43 years), coming as close as 0.53 AU and reaching as far as 2.01 AU from the sun. Based on its brightness and the way it reflects light, 1993 EA is probably between 1.166 to 2.606 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.

The rotation of 1993 EA has been observed. It completes a rotation on its axis every 2.50 hours.

Close Approaches

1993 EA's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

1993 EA has 16 close approaches predicted in the coming decades:
