Overview

405762 (2005 YO180) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2005 YO180 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2005 YO180 orbits the sun every 658 days (1.80 years), coming as close as 0.82 AU and reaching as far as 2.14 AU from the sun. Based on its brightness and the way it reflects light, 2005 YO180 is probably between 0.234 to 0.522 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to a football field.

Close Approaches

2005 YO180's orbit is 0.04 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.

2005 YO180 has 9 close approaches predicted in the coming decades:
