Asteroid Apophis: evolution of the orbit and the possible use. Space Colonization Journal, Issue 2, 2014.


Based on the analysis of available scientific datasets, the author found that a number of uncertainties in the trajectory of Apophis is caused by imperfections of methods for its determination. A new numerical method was used to integrate differential equations of motion of Apophis, planets, the moon and the sun and the evolution of the asteroid’s orbit was studied. In April 13, 2029 Apophis will pass by the Earth at a distance of 6 of its radius and within 1,000 years it will not come closer. Conditions to transform Apophis into an Earth satellite are calculated; it can be used for a variety of space exploration tasks.
