Clifford is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified Clifford as potentially hazardous because its orbit does not bring it close to Earth.
Clifford orbits the sun every 1,040 days (2.85 years), coming as close as 1.60 AU and reaching as far as 2.42 AU from the sun. Clifford is about 4.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
The rotation of Clifford has been observed. It completes a rotation on its axis every 3.24 hours.
Clifford's orbit is 0.62 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.
Clifford's orbit is determined by observations dating back to Oct. 5, 1981. It was last officially observed on June 25, 2022. The IAU Minor Planet Center records 2,120 observations used to determine its orbit.
