Overview

447755 (2007 JX2) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 JX2 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2007 JX2 orbits the sun every 816 days (2.23 years), coming as close as 0.81 AU and reaching as far as 2.61 AU from the sun. Based on its brightness and the way it reflects light, 2007 JX2 is probably between 0.295 to 0.661 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

Close Approaches

2007 JX2'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.

2007 JX2 has 13 close approaches predicted in the coming decades:
