2016 RB1 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2016 RB1 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 RB1 orbits the sun every 298 days (0.82 years), coming as close as 0.63 AU and reaching as far as 1.12 AU from the sun. Based on its brightness and the way it reflects light, 2016 RB1 is probably between 0.004 to 0.017 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
The rotation of 2016 RB1 has been observed. It completes a rotation on its axis every 0.03 hours.
2016 RB1's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.
2016 RB1 has 18 close approaches predicted in the coming decades:

2016 RB1's orbit is determined by observations dating back to Sept. 5, 2016. It was last officially observed on Sept. 7, 2016. The IAU Minor Planet Center records 155 observations used to determine its orbit.
2016 RB1 can be reached with a journey of 322 days. This trajectory would require a delta-v of 8.541 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 95,521 potential trajectories and launch windows to this asteroid.
