Overview

380636 (2004 XN14) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2004 XN14 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2004 XN14 orbits the sun every 328 days (0.90 years), coming as close as 0.68 AU and reaching as far as 1.18 AU from the sun. Based on its brightness and the way it reflects light, 2004 XN14 is probably between 0.297 to 0.664 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

2004 XN14'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.

2004 XN14 has 26 close approaches predicted in the coming decades:
