23123 (2000 AU57) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2000 AU57 as potentially hazardous because its orbit does not bring it close to Earth.
2000 AU57 orbits the sun every 4,510 days (12.35 years), coming as close as 5.02 AU and reaching as far as 5.66 AU from the sun. 2000 AU57 is about 25.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.
The rotation of 2000 AU57 has been observed. It completes a rotation on its axis every 467.26 hours.
2000 AU57's orbit is 4.05 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.
2000 AU57's orbit is determined by observations dating back to Feb. 27, 1976. It was last officially observed on April 8, 2023. The IAU Minor Planet Center records 1,760 observations used to determine its orbit.
