1999 DO8 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1999 DO8 as potentially hazardous because its orbit does not bring it close to Earth.
1999 DO8 orbits the sun every 98,700 days (270.23 years), coming as close as 41.79 AU and reaching as far as 41.79 AU from the sun. Based on its brightness and the way it reflects light, 1999 DO8 is probably between 26.095 to 58.350 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of New York.
1999 DO8's orbit is 40.80 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.
1999 DO8's orbit is determined by observations dating back to Feb. 16, 1999. It was last officially observed on Feb. 17, 1999. The IAU Minor Planet Center records 4 observations used to determine its orbit.
