155725 (2000 RO8) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 2000 RO8 as potentially hazardous because its orbit does not bring it close to Earth.
2000 RO8 orbits the sun every 1,030 days (2.82 years), coming as close as 1.31 AU and reaching as far as 2.68 AU from the sun. Based on its brightness and the way it reflects light, 2000 RO8 is probably between 1.029 to 2.302 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.
2000 RO8's orbit is 0.39 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.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
2000 RO8's orbit is determined by observations dating back to March 24, 1993. It was last officially observed on June 29, 2022. The IAU Minor Planet Center records 699 observations used to determine its orbit.
