Overview

529951 (2010 UD) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 UD as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2010 UD orbits the sun every 420 days (1.15 years), coming as close as 0.81 AU and reaching as far as 1.39 AU from the sun. Based on its brightness and the way it reflects light, 2010 UD is probably between 0.162 to 0.361 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2010 UD'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 UD has 20 close approaches predicted in the coming decades:
