Overview

2014 WA201 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 WA201 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.

2014 WA201 orbits the sun every 619 days (1.69 years), coming as close as 0.82 AU and reaching as far as 2.02 AU from the sun. Based on its brightness and the way it reflects light, 2014 WA201 is probably between 0.012 to 0.026 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2014 WA201's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.

2014 WA201 has 1 close approaches predicted in the coming decades:
