Overview
2016 NT22 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2016 NT22 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2016 NT22 orbits the sun every 508 days (1.39 years), coming as close as 0.16 AU and reaching as far as 2.33 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2016 NT22 is probably between 0.330 to 0.738 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
2016 NT22's orbit is 0.01 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.
2016 NT22 has 9 close approaches predicted in the coming decades:
