Demoleon is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified Demoleon as potentially hazardous because its orbit does not bring it close to Earth.
Demoleon orbits the sun every 4,440 days (12.16 years), coming as close as 4.79 AU and reaching as far as 5.77 AU from the sun. Demoleon is about 33.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of New York.
The rotation of Demoleon has been observed. It completes a rotation on its axis every 14.43 hours.
Demoleon's orbit is 3.84 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.
Demoleon's orbit is determined by observations dating back to Nov. 4, 1989. It was last officially observed on June 27, 2023. The IAU Minor Planet Center records 2,801 observations used to determine its orbit.
