2016 PD1 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2016 PD1 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 PD1 orbits the sun every 544 days (1.49 years), coming as close as 1.02 AU and reaching as far as 1.59 AU from the sun. Based on its brightness and the way it reflects light, 2016 PD1 is probably between 0.030 to 0.135 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2016 PD1's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.
2016 PD1 has 11 close approaches predicted in the coming decades:

2016 PD1's orbit is determined by observations dating back to Aug. 2, 2016. It was last officially observed on Aug. 30, 2019. The IAU Minor Planet Center records 109 observations used to determine its orbit.
2016 PD1 can be reached with a journey of 370 days. This trajectory would require a delta-v of 11.042 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 155 potential trajectories and launch windows to this asteroid.
