Overview

2019 OQ2 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 OQ2 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2019 OQ2 orbits the sun every 636 days (1.74 years), coming as close as 0.57 AU and reaching as far as 2.32 AU from the sun. Based on its brightness and the way it reflects light, 2019 OQ2 is probably between 0.238 to 0.532 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to a football field.

Close Approaches

2019 OQ2's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2019 OQ2 has 15 close approaches predicted in the coming decades:
