2014 UR is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2014 UR 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 UR orbits the sun every 360 days (0.99 years), coming as close as 0.98 AU and reaching as far as 1.01 AU from the sun. Based on its brightness and the way it reflects light, 2014 UR is probably between 0.008 to 0.037 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
The rotation of 2014 UR has been observed. It completes a rotation on its axis every 0.23 hours.
2014 UR's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2014 UR has 39 close approaches predicted in the coming decades:

2014 UR's orbit is determined by observations dating back to Oct. 17, 2014. It was last officially observed on Oct. 25, 2015. The IAU Minor Planet Center records 231 observations used to determine its orbit.
2014 UR can be reached with a journey of 370 days. This trajectory would require a delta-v of 6.206 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 133,392 potential trajectories and launch windows to this asteroid.
