30506 (2000 RO85) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2000 RO85 as potentially hazardous because its orbit does not bring it close to Earth.
2000 RO85 orbits the sun every 4,240 days (11.61 years), coming as close as 4.70 AU and reaching as far as 5.55 AU from the sun. 2000 RO85 is about 34.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of New York.
The rotation of 2000 RO85 has been observed. It completes a rotation on its axis every 7.99 hours.
2000 RO85's orbit is 3.70 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
2000 RO85's orbit is determined by observations dating back to Oct. 1, 1953. It was last officially observed on June 23, 2023. The IAU Minor Planet Center records 2,118 observations used to determine its orbit.
