Overview

468910 (2014 KQ76) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 KQ76 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2014 KQ76 orbits the sun every 369 days (1.01 years), coming as close as 0.58 AU and reaching as far as 1.43 AU from the sun. Based on its brightness and the way it reflects light, 2014 KQ76 is probably between 0.123 to 0.275 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.

The rotation of 2014 KQ76 has been observed. It completes a rotation on its axis every 2.95 hours.

Close Approaches

2014 KQ76's orbit is 0.04 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.

2014 KQ76 has 24 close approaches predicted in the coming decades:
