(53319) 1999 JM8 (also written (53319) 1999 JM8) is a Potentially hazardous asteroid, near-Earth asteroid and Mars-crosser asteroid discovered by LINEAR. Radar imaging by Goldstone and Arecibo has revealed the asteroid to have an effective diameter of 6.4 km. Like the asteroid 4179 Toutatis, its rotation speed is unusually slow and possibly chaotic. It is the largest Potentially hazardous object known.

It passed closer than 0.20 AU to the Earth five times in the last century (0.033 AU in 1990), but its closest approach in the 21st century will be in 2075 at 0.256 AU.
