2014 WX202 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 WX202 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 WX202 orbits the sun every 385 days (1.05 years), coming as close as 0.98 AU and reaching as far as 1.10 AU from the sun. Based on its brightness and the way it reflects light, 2014 WX202 is probably between 0.002 to 0.009 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2014 WX202'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.

2014 WX202's orbit is determined by observations dating back to Nov. 24, 2014. It was last officially observed on Dec. 8, 2014. The IAU Minor Planet Center records 44 observations used to determine its orbit.
2014 WX202 can be reached with a journey of 370 days. This trajectory would require a delta-v of 4.256 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 1,139,166 potential trajectories and launch windows to this asteroid.
