Revisiting Apophis 2029 approach to Earth (staying on shoulders of NASA's experts) or Can we be sure in almost ricocheting fly-by of Apophis on 13 of April 2029 near the Earth?

The main idea of this challenging research is to revisit the solar-centric dynamics Earth around Sun in analysis its position on 13 April 2029 close asteroid Apophis which supposed be moving fly-by near orbit. As now, we can sure that trajectory well-known with respect center Sun. Also, NASA experts calculated relative distance between and should less than 38 thousand kilometers during closest approach Earth. But reasonable question is: will at predicted beginning 2029? matter solving procedure disregards influence Milankovitch cycles orbit but alternative concept suggests another solution (with additional quasi-periodic deviation from their solution, proportional square eccentricity Earth's equals ∼ 0.017). So, possible perturbation likely (0.017)² 0.03% 1 a.u. or 43 200 km could compared gap 2029.
