Overview
357024 (1999 YR14) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1999 YR14 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
1999 YR14 orbits the sun every 775 days (2.12 years), coming as close as 0.99 AU and reaching as far as 2.31 AU from the sun. 1999 YR14 is about 0.3 kilometers in diameter, making it a small to average asteroid, comparable in size to a football field.
The rotation of 1999 YR14 has been observed. It completes a rotation on its axis every 4.25 hours.
