Kley is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Kley as potentially hazardous because its orbit does not bring it close to Earth.
Kley orbits the sun every 2,010 days (5.50 years), coming as close as 2.66 AU and reaching as far as 3.57 AU from the sun. Kley is about 25.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.
The rotation of Kley has been observed. It completes a rotation on its axis every 12.52 hours.
Kley's orbit is 1.67 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.
Kley's orbit is determined by observations dating back to June 6, 1969. It was last officially observed on May 29, 2023. The IAU Minor Planet Center records 3,840 observations used to determine its orbit.
