Overview
2014 YD is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 YD 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 YD orbits the sun every 406 days (1.11 years), coming as close as 0.98 AU and reaching as far as 1.16 AU from the sun. Based on its brightness and the way it reflects light, 2014 YD is probably between 0.024 to 0.107 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 YD has been observed. It completes a rotation on its axis every 2.12 hours.
Close Approaches
2014 YD'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 YD has 12 close approaches predicted in the coming decades:

Images and Observations
2014 YD's orbit is determined by observations dating back to Dec. 6, 2014. It was last officially observed on June 18, 2015. The IAU Minor Planet Center records 106 observations used to determine its orbit.
Accessibility and Exploration
2014 YD can be reached with a journey of 362 days. This trajectory would require a delta-v of 5.267 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 918,683 potential trajectories and launch windows to this asteroid.
