Overview

2010 JG is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 JG as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2010 JG orbits the sun every 474 days (1.30 years), coming as close as 0.81 AU and reaching as far as 1.57 AU from the sun. 2010 JG is about 0.2 kilometers in diameter, making it a small to average asteroid, comparable in size to a football field.

Close Approaches

2010 JG's orbit is 0.03 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.

2010 JG has 18 close approaches predicted in the coming decades:
