Overview
90416 (2003 YK118) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2003 YK118 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2003 YK118 orbits the sun every 806 days (2.21 years), coming as close as 0.86 AU and reaching as far as 2.53 AU from the sun. 2003 YK118 is about 1.0 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.
The rotation of 2003 YK118 has been observed. It completes a rotation on its axis every 43.58 hours.
