129140 (2005 AO50) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2005 AO50 as potentially hazardous because its orbit does not bring it close to Earth.
2005 AO50 orbits the sun every 4,310 days (11.80 years), coming as close as 5.10 AU and reaching as far as 5.27 AU from the sun. 2005 AO50 is about 16.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.
The rotation of 2005 AO50 has been observed. It completes a rotation on its axis every 9.38 hours.
2005 AO50's orbit is 4.09 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.
2005 AO50's orbit is determined by observations dating back to Sept. 24, 2000. It was last officially observed on May 23, 2023. The IAU Minor Planet Center records 594 observations used to determine its orbit.
