Overview

2016 EG28 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2016 EG28 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 EG28 orbits the sun every 889 days (2.43 years), coming as close as 0.78 AU and reaching as far as 2.84 AU from the sun. Based on its brightness and the way it reflects light, 2016 EG28 is probably between 0.007 to 0.016 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2016 EG28's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2016 EG28 has 1 close approaches predicted in the coming decades:
