66063 (1998 RO1) is a 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 0.623 to 1.393 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, 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 hours.
1998 RO1's orbit is 0.09 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.
