129134 (2005 AC5) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2005 AC5 as potentially hazardous because its orbit does not bring it close to Earth.
2005 AC5 orbits the sun every 4,340 days (11.88 years), coming as close as 4.86 AU and reaching as far as 5.55 AU from the sun. Based on its brightness and the way it reflects light, 2005 AC5 is probably between 9.388 to 20.991 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Cleveland, Ohio.
2005 AC5's orbit is 3.85 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 AC5's orbit is determined by observations dating back to Aug. 5, 2000. It was last officially observed on June 28, 2023. The IAU Minor Planet Center records 644 observations used to determine its orbit.
