Overview
2016 ED156 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2016 ED156 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 ED156 orbits the sun every 306 days (0.84 years), coming as close as 0.50 AU and reaching as far as 1.28 AU from the sun. Based on its brightness and the way it reflects light, 2016 ED156 is probably between 0.052 to 0.115 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2016 ED156's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.
2016 ED156 has 29 close approaches predicted in the coming decades:
