38617 (2000 AY161) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2000 AY161 as potentially hazardous because its orbit does not bring it close to Earth.
2000 AY161 orbits the sun every 4,340 days (11.88 years), coming as close as 4.99 AU and reaching as far as 5.43 AU from the sun. 2000 AY161 is about 16.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.
The rotation of 2000 AY161 has been observed. It completes a rotation on its axis every 10.70 hours.
2000 AY161's orbit is 4.02 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 AY161's orbit is determined by observations dating back to Aug. 18, 1995. It was last officially observed on Jan. 22, 2023. The IAU Minor Planet Center records 982 observations used to determine its orbit.
