Overview

2010 XB24 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 XB24 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2010 XB24 orbits the sun every 533 days (1.46 years), coming as close as 0.72 AU and reaching as far as 1.85 AU from the sun. Based on its brightness and the way it reflects light, 2010 XB24 is probably between 0.116 to 0.259 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.

Close Approaches

2010 XB24'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 XB24 has 19 close approaches predicted in the coming decades:
