Klio is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Klio as potentially hazardous because its orbit does not bring it close to Earth.
Klio orbits the sun every 1,330 days (3.64 years), coming as close as 1.80 AU and reaching as far as 2.92 AU from the sun. Klio is about 79.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Delaware.
The rotation of Klio has been observed. It completes a rotation on its axis every 23.56 hours.
Klio's spectral type G (Tholen) / Ch (SMASSII) indicates that it is likely to contain water, iron, nickel, cobalt, nitrogen, and ammonia.
Klio's orbit is 0.80 AU from Earth's orbit at its closest point. This means that there is a very 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.
Klio's orbit is determined by observations dating back to Aug. 25, 1865. It was last officially observed on June 8, 2023. The IAU Minor Planet Center records 3,895 observations used to determine its orbit.
