Overview
2010 KD149 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2010 KD149 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2010 KD149 orbits the sun every 306 days (0.84 years), coming as close as 0.70 AU and reaching as far as 1.08 AU from the sun. 2010 KD149 is about 0.2 kilometers in diameter, making it a small to average asteroid, comparable in size to a football field.
Close Approaches
2010 KD149'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.
2010 KD149 has 17 close approaches predicted in the coming decades:
