We use an improved explicit symplectic algorithm and a nested RKF7(8) integrator to make a numerical study of the orbital evolution of 86 numbered near-Earth asteroids. We give their status of evolution on times scales of 103-104 yr and their minimum distances to some of the major planets. Some of the minimum distances to Earth can be less than 0.01 au, or even less than the distance of the Moon.
