15540 (2000 CF18) is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 2000 CF18 as potentially hazardous because its orbit does not bring it close to Earth.
2000 CF18 orbits the sun every 2,900 days (7.94 years), coming as close as 3.55 AU and reaching as far as 4.42 AU from the sun. 2000 CF18 is about 19.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Denver.
The rotation of 2000 CF18 has been observed. It completes a rotation on its axis every 28.41 hours.
2000 CF18's orbit is 2.60 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.
2000 CF18's orbit is determined by observations dating back to June 1, 1954. It was last officially observed on March 23, 2023. The IAU Minor Planet Center records 2,224 observations used to determine its orbit.
