About Zones of Resonant Returns of Asteroid Apophis . ... Asteroid Apophis is one of extremely dangerous NEOs. ... Using analytical and numerical tools, we investigate the loss of precision after the Earth approach in 2029 and the possible approach in 2036. ... Possible trajectories of collisions with the Earth have been found analytically and numerically in this chaotic region. To construct these trajectories we used quasi-random intermediate motions, made up from resonant collision orbits. ...
