Pallas is a very large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Pallas as potentially hazardous because its orbit does not bring it close to Earth.
Pallas orbits the sun every 1,686 days (4.62 years), coming as close as 2.13 AU and reaching as far as 3.41 AU from the sun. Pallas is about 545.0 kilometers in diameter, making it one of the largest asteroids, comparable in size to Great Britain.
The rotation of Pallas has been observed. It completes a rotation on its axis every 7.81 days.
Pallas's orbit is 1.23 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.
Pallas's orbit is determined by observations dating back to May 9, 1821. It was last officially observed on Feb. 10, 2018. The IAU Minor Planet Center records 8,441 observations used to determine its orbit.
