Antilochus is a average-sized asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified Antilochus as potentially hazardous because its orbit does not bring it close to Earth.
Antilochus orbits the sun every 4,250 days (11.64 years), coming as close as 4.86 AU and reaching as far as 5.40 AU from the sun. Antilochus is about 108.8 kilometers in diameter, making it larger than most asteroids, comparable in size to the U.S. state of Delaware.
The rotation of Antilochus has been observed. It completes a rotation on its axis every 15.89 days.
Antilochus's orbit is 3.87 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.
Antilochus's orbit is determined by observations dating back to Nov. 10, 1926. It was last officially observed on Dec. 4, 2019. The IAU Minor Planet Center records 2,412 observations used to determine its orbit.
