Overview

465892 (2010 UT7) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 UT7 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2010 UT7 orbits the sun every 728 days (1.99 years), coming as close as 0.54 AU and reaching as far as 2.63 AU from the sun. Based on its brightness and the way it reflects light, 2010 UT7 is probably between 0.311 to 0.695 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 UT7'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 UT7 has 25 close approaches predicted in the coming decades:
