2018 RO5 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2018 RO5 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.
2018 RO5 orbits the sun every 361 days (0.99 years), coming as close as 0.76 AU and reaching as far as 1.22 AU from the sun. Based on its brightness and the way it reflects light, 2018 RO5 is probably between 0.130 to 0.590 kilometers in diameter, making it small in absolute terms, but larger than 90% of asteroids, very roughly comparable in size to the U.S. Capitol building.
2018 RO5'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.

2018 RO5's orbit is determined by observations dating back to Sept. 12, 2018. It was last officially observed on Oct. 6, 2018. The IAU Minor Planet Center records 102 observations used to determine its orbit.
2018 RO5 can be reached with a journey of 394 days. This trajectory would require a delta-v of 7.301 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 417,974 potential trajectories and launch windows to this asteroid.
