Overview
2010 EX11 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2010 EX11 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.
2010 EX11 orbits the sun every 341 days (0.93 years), coming as close as 0.85 AU and reaching as far as 1.06 AU from the sun. 2010 EX11 is about 0.0 kilometers in diameter, making it a small to average asteroid, comparable in size to a school bus or smaller.
The rotation of 2010 EX11 has been observed. It completes a rotation on its axis every 9.40 hours.
Close Approaches
2010 EX11's orbit is 0.03 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.
2010 EX11 has 18 close approaches predicted in the coming decades:
