315530 (2008 AP129) is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2008 AP129 as potentially hazardous because its orbit does not bring it close to Earth.
2008 AP129 orbits the sun every 98,500 days (269.68 years), coming as close as 35.86 AU and reaching as far as 47.62 AU from the sun. Based on its brightness and the way it reflects light, 2008 AP129 is probably between 273.247 to 610.998 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to the U.S. state of Pennsylvania.
The rotation of 2008 AP129 has been observed. It completes a rotation on its axis every 9.04 hours.
2008 AP129's orbit is 34.90 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.
2008 AP129's orbit is determined by observations dating back to Oct. 9, 1989. It was last officially observed on April 7, 2023. The IAU Minor Planet Center records 328 observations used to determine its orbit.
