Overview

2019 NN36 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 NN36 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2019 NN36 orbits the sun every 681 days (1.86 years), coming as close as 0.83 AU and reaching as far as 2.20 AU from the sun. Based on its brightness and the way it reflects light, 2019 NN36 is probably between 0.305 to 0.682 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

Close Approaches

2019 NN36's orbit is 0.12 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 NN36 has 13 close approaches predicted in the coming decades:
