Overview

523685 (2014 DN112) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 DN112 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2014 DN112 orbits the sun every 918 days (2.51 years), coming as close as 0.93 AU and reaching as far as 2.76 AU from the sun. Based on its brightness and the way it reflects light, 2014 DN112 is probably between 0.261 to 0.583 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

2014 DN112's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
