34684 (2001 CJ28) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2001 CJ28 as potentially hazardous because its orbit does not bring it close to Earth.
2001 CJ28 orbits the sun every 4,340 days (11.88 years), coming as close as 4.55 AU and reaching as far as 5.87 AU from the sun. Based on its brightness and the way it reflects light, 2001 CJ28 is probably between 10.828 to 24.213 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Cleveland, Ohio.
2001 CJ28's orbit is 3.64 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.
2001 CJ28's orbit is determined by observations dating back to Nov. 28, 1951. It was last officially observed on March 2, 2023. The IAU Minor Planet Center records 1,281 observations used to determine its orbit.
