Overview

2017 UX5 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 UX5 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2017 UX5 orbits the sun every 488 days (1.34 years), coming as close as 0.92 AU and reaching as far as 1.51 AU from the sun. Based on its brightness and the way it reflects light, 2017 UX5 is probably between 0.294 to 0.658 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

2017 UX5's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2017 UX5 has 6 close approaches predicted in the coming decades:
