Overview

2009 QJ9 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2009 QJ9 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2009 QJ9 orbits the sun every 1,640 days (4.49 years), coming as close as 1.03 AU and reaching as far as 4.40 AU from the sun. Based on its brightness and the way it reflects light, 2009 QJ9 is probably between 0.372 to 0.832 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

2009 QJ9's orbit is 0.05 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.

2009 QJ9 has 1 close approaches predicted in the coming decades:
