Overview

2016 ED85 is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2016 ED85 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2016 ED85 orbits the sun every 1,890 days (5.17 years), coming as close as 0.91 AU and reaching as far as 5.06 AU from the sun. Based on its brightness and the way it reflects light, 2016 ED85 is probably between 0.788 to 1.762 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the Golden Gate Bridge.

The rotation of 2016 ED85 has been observed. It completes a rotation on its axis every 3.22 hours.

Close Approaches

2016 ED85's orbit is 0.08 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.

2016 ED85 has 2 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Oct. 6, 2020 28,138,132 18.261
Jan. 20, 2098 15,768,447 14.977

Images and Observations

2016 ED85's orbit is determined by observations dating back to Oct. 8, 1989. It was last officially observed on May 3, 2021. The IAU Minor Planet Center records 840 observations used to determine its orbit.
