66063 (1998 RO1) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 1998 RO1 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.
1998 RO1 orbits the sun every 360 days (0.99 years), coming as close as 0.28 AU and reaching as far as 1.70 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 1998 RO1 is probably between 0.638 to 1.426 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to the Golden Gate Bridge.
The rotation of 1998 RO1 has been observed. It completes a rotation on its axis every 2.49 days.
1998 RO1's orbit is 0.09 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
