156210 (2001 UH57) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2001 UH57 as potentially hazardous because its orbit does not bring it close to Earth.
2001 UH57 orbits the sun every 4,300 days (11.77 years), coming as close as 4.77 AU and reaching as far as 5.58 AU from the sun. 2001 UH57 is about 17.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.
2001 UH57's orbit is 3.78 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 UH57's orbit is determined by observations dating back to Jan. 13, 1994. It was last officially observed on June 22, 2023. The IAU Minor Planet Center records 385 observations used to determine its orbit.
