Overview

2010 XB11 is a very small asteroid with an orbit that is entirely confined within Earth's orbit. NASA JPL has classified 2010 XB11 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 XB11 orbits the sun every 177 days (0.48 years), coming as close as 0.29 AU and reaching as far as 0.95 AU from the sun. Based on its brightness and the way it reflects light, 2010 XB11 is probably between 0.278 to 0.622 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

Close Approaches

2010 XB11's orbit is 0.09 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2010 XB11 has 27 close approaches predicted in the coming decades:
