Overview

163015 (2001 UX16) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2001 UX16 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.

2001 UX16 orbits the sun every 616 days (1.69 years), coming as close as 0.90 AU and reaching as far as 1.94 AU from the sun. Based on its brightness and the way it reflects light, 2001 UX16 is probably between 0.102 to 0.229 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2001 UX16's orbit is 0.06 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.

2001 UX16 has 12 close approaches predicted in the coming decades:
