Overview

413577 (2005 UL5) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2005 UL5 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2005 UL5 orbits the sun every 331 days (0.91 years), coming as close as 0.40 AU and reaching as far as 1.47 AU from the sun. Based on its brightness and the way it reflects light, 2005 UL5 is probably between 0.227 to 0.508 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

The rotation of 2005 UL5 has been observed. It completes a rotation on its axis every 3.46 hours.

Close Approaches

2005 UL5'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.

2005 UL5 has 12 close approaches predicted in the coming decades:
