Overview

2004 RY10 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2004 RY10 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2004 RY10 orbits the sun every 793 days (2.17 years), coming as close as 0.63 AU and reaching as far as 2.72 AU from the sun. Based on its brightness and the way it reflects light, 2004 RY10 is probably between 0.139 to 0.312 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2004 RY10'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.

2004 RY10 has 12 close approaches predicted in the coming decades:
