Overview

53789 (2000 ED104) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 ED104 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2000 ED104 orbits the sun every 586 days (1.60 years), coming as close as 1.00 AU and reaching as far as 1.74 AU from the sun. 2000 ED104 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 ED104 has been observed. It completes a rotation on its axis every 43.00 days.

Close Approaches

2000 ED104's orbit is 0.05 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.
