Overview
2013 ED28 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 ED28 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2013 ED28 orbits the sun every 705 days (1.93 years), coming as close as 0.52 AU and reaching as far as 2.58 AU from the sun. Based on its brightness and the way it reflects light, 2013 ED28 is probably between 0.133 to 0.298 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
Close Approaches
2013 ED28's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.
2013 ED28 has 13 close approaches predicted in the coming decades:
