Аннотация

Analysis of publications establishes that the uncertainty of trajectories of Apophis are caused by imperfections in the methods of its determination. The differential equations of motion of Apophis, planets, the Moon, and the Sun are integrated by new numerical methods and the evolution of the asteroid orbit is investigated. Apophis will pass by the Earth at a distance of 6.1 Earth radii on April 13th, 2029. It will be its closest approach to Earth during the next 1000 years. The possibility of transforming Apophis' orbit to an Earth satellite orbit that could be used for various tasks, is considered
