Achilles is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified Achilles as potentially hazardous because its orbit does not bring it close to Earth.
Achilles orbits the sun every 4,340 days (11.88 years), coming as close as 4.44 AU and reaching as far as 5.98 AU from the sun. Achilles is about 130.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Connecticut.
The rotation of Achilles has been observed. It completes a rotation on its axis every 7.31 hours.
Achilles's orbit is 3.47 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.
Achilles's orbit is determined by observations dating back to Feb. 22, 1906. It was last officially observed on Jan. 20, 2021. The IAU Minor Planet Center records 2,404 observations used to determine its orbit.
