Chiron is a average-sized asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified Chiron as potentially hazardous because its orbit does not bring it close to Earth.
Chiron orbits the sun every 18,459 days (50.54 years), coming as close as 8.47 AU and reaching as far as 18.87 AU from the sun. Chiron is about 166.0 kilometers in diameter, making it larger than most asteroids, comparable in size to the U.S. state of Massachusetts.
The rotation of Chiron has been observed. It completes a rotation on its axis every 5.92 days.
Chiron's orbit is 7.47 AU from Earth's orbit at its closest point. This means that there is a 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.
Chiron's orbit is determined by observations dating back to April 24, 1895. It was last officially observed on Sept. 18, 2018. The IAU Minor Planet Center records 2,184 observations used to determine its orbit.
