Overview

614433 (2009 KK) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2009 KK as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2009 KK orbits the sun every 672 days (1.84 years), coming as close as 0.82 AU and reaching as far as 2.19 AU from the sun. Based on its brightness and the way it reflects light, 2009 KK is probably between 0.203 to 0.455 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2009 KK's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.

2009 KK has 7 close approaches predicted in the coming decades:
