Overview

410627 (2008 RG1) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2008 RG1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2008 RG1 orbits the sun every 551 days (1.51 years), coming as close as 0.73 AU and reaching as far as 1.90 AU from the sun. Based on its brightness and the way it reflects light, 2008 RG1 is probably between 0.176 to 0.394 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2008 RG1's orbit is 0.01 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.

2008 RG1 has 16 close approaches predicted in the coming decades:
