40262 (1999 CF156) is a mid-sized asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1999 CF156 as potentially hazardous because its orbit does not bring it close to Earth.
1999 CF156 orbits the sun every 4,390 days (12.02 years), coming as close as 4.44 AU and reaching as far as 6.05 AU from the sun. Based on its brightness and the way it reflects light, 1999 CF156 is probably between 6.615 to 14.792 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
1999 CF156's orbit is 3.47 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.
1999 CF156's orbit is determined by observations dating back to May 13, 1990. It was last officially observed on Jan. 24, 2023. The IAU Minor Planet Center records 562 observations used to determine its orbit.
