132524 APL, provisional designation 2002 JF56, is a stony background asteroid in the intermediate asteroid belt, approximately 2.3 kilometers across. It was imaged by the New Horizons space probe on its flyby in 2006.


It was discovered on 9 May 2002 by astronomers of the Lincoln Near-Earth Asteroid Research (LINEAR) at the Lincoln Laboratory's ETS near Socorro, New Mexico, United States.[1] The asteroid orbits the Sun in a somewhat eccentric orbit at a distance of 1.9–3.3 AU once every 4.2 years. Its orbit is tilted off the ecliptic by 4 degrees.[1]

The New Horizons probe flew by it at a distance of approximately 102,000 kilometers on 13 June 2006. The spectra obtained by New Horizons show that APL is a stony S-type asteroid.[2]

New Horizons was not intended to fly by APL, and the flyby was just a coincidence. Alan Stern, principal investigator for New Horizons, named the asteroid in reference to the Johns Hopkins University Applied Physics Laboratory (APL), which runs the mission.[3]
