Overview

2019 KQ5 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 KQ5 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2019 KQ5 orbits the sun every 802 days (2.20 years), coming as close as 0.67 AU and reaching as far as 2.71 AU from the sun. Based on its brightness and the way it reflects light, 2019 KQ5 is probably between 0.121 to 0.272 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.

Close Approaches

2019 KQ5'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.

2019 KQ5 has 11 close approaches predicted in the coming decades:
