39289 (2001 CT28) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2001 CT28 as potentially hazardous because its orbit does not bring it close to Earth.
2001 CT28 orbits the sun every 4,400 days (12.05 years), coming as close as 5.01 AU and reaching as far as 5.50 AU from the sun. 2001 CT28 is about 13.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.
The rotation of 2001 CT28 has been observed. It completes a rotation on its axis every 19.06 hours.
2001 CT28's orbit is 4.04 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 CT28's orbit is determined by observations dating back to Oct. 7, 1996. It was last officially observed on Jan. 11, 2023. The IAU Minor Planet Center records 701 observations used to determine its orbit.
