138031 (2000 DK9) is a mid-sized asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2000 DK9 as potentially hazardous because its orbit does not bring it close to Earth.
2000 DK9 orbits the sun every 4,440 days (12.16 years), coming as close as 5.08 AU and reaching as far as 5.48 AU from the sun. Based on its brightness and the way it reflects light, 2000 DK9 is probably between 5.402 to 12.079 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
2000 DK9's orbit is 4.10 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 DK9's orbit is determined by observations dating back to Feb. 2, 2000. It was last officially observed on April 18, 2023. The IAU Minor Planet Center records 483 observations used to determine its orbit.
