Overview

2019 NE2 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 NE2 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2019 NE2 orbits the sun every 831 days (2.28 years), coming as close as 0.47 AU and reaching as far as 2.99 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2019 NE2 is probably between 0.163 to 0.364 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2019 NE2's orbit is 0.05 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2019 NE2 has 10 close approaches predicted in the coming decades:
