Domeyko is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Domeyko as potentially hazardous because its orbit does not bring it close to Earth.
Domeyko orbits the sun every 1,230 days (3.37 years), coming as close as 1.85 AU and reaching as far as 2.63 AU from the sun. Based on its brightness and the way it reflects light, Domeyko is probably between 6.801 to 15.207 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
The rotation of Domeyko has been observed. It completes a rotation on its axis every 6.03 hours.
Domeyko's orbit is 0.84 AU from Earth's orbit at its closest point. This means that there is a very 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.
Domeyko's orbit is determined by observations dating back to Oct. 6, 1959. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 3,366 observations used to determine its orbit.
