2002 CY154 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2002 CY154 as potentially hazardous because its orbit does not bring it close to Earth.
2002 CY154 orbits the sun every 107,000 days (292.95 years), coming as close as 40.45 AU and reaching as far as 47.73 AU from the sun. Based on its brightness and the way it reflects light, 2002 CY154 is probably between 121.494 to 271.669 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Vermont.
2002 CY154's orbit is 39.40 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.
2002 CY154's orbit is determined by observations dating back to Feb. 6, 2002. It was last officially observed on March 20, 2021. The IAU Minor Planet Center records 25 observations used to determine its orbit.
