33001 (1997 CU29) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1997 CU29 as potentially hazardous because its orbit does not bring it close to Earth.
1997 CU29 orbits the sun every 104,000 days (284.74 years), coming as close as 41.77 AU and reaching as far as 44.93 AU from the sun. Based on its brightness and the way it reflects light, 1997 CU29 is probably between 138.215 to 309.058 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Massachusetts.
1997 CU29's orbit is 40.80 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.
1997 CU29's orbit is determined by observations dating back to Feb. 6, 1997. It was last officially observed on Jan. 30, 2020. The IAU Minor Planet Center records 177 observations used to determine its orbit.
