Asteroid Apophis is now one of extremely dangerous NEO. Different scenarios of the Apophis’ orbit dynamical evolution in frames of today knowledge of its orbit is discussed. Using analytical and numerical tools, we investigate a precision loss after approach with the Earth in 2029 and possible approach in 2036. After 2036 the Apophis motion may be non-determinable. Possible trajectories of collisions with the Earth have been found analytically and numerically in this chaotic region. To construct these trajectories we use quasi-random intermediate motions, made up from resonant collision orbits. The hazard trajectories are derived numerically using Everhart integrator and Solar System model DE405. The size of initial conditions regions leading to the collisions in 2040, 2041, 2042, 2044, 2047, 2051 is presented. The possibility of similar behaviour of other NEO trajectories is discussed.
