2016 HF2 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2016 HF2 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.
2016 HF2 orbits the sun every 359 days (0.98 years), coming as close as 0.80 AU and reaching as far as 1.18 AU from the sun. Based on its brightness and the way it reflects light, 2016 HF2 is probably between 0.010 to 0.047 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2016 HF2'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.
2016 HF2 has 10 close approaches predicted in the coming decades:

2016 HF2's orbit is determined by observations dating back to April 25, 2016. It was last officially observed on May 4, 2016. The IAU Minor Planet Center records 77 observations used to determine its orbit.
2016 HF2 can be reached with a journey of 370 days. This trajectory would require a delta-v of 6.579 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 248,448 potential trajectories and launch windows to this asteroid.
