Calculations of the orbital evolution of two major objects of the main asteroid belt, the dwarf planet Ceres ans the asteroid Vesta. showed that in the future they may collide.The collide of Ceres and Vesta possible with a probability of 0.2% per billion years. Laskar and his colleagues conducted computer simulations of the evolution of the solar system, considering the behavior of the eight planets, Pluto, Ceres, and the four largest asteroids Pallas, Vesta, Iris and Bamberg, located in the main asteroid belt between Mars and Jupiter. Analysis of the gravitational interactions of these celestial bodies showed that the convergence of the asteroids in a very short time in astronomical terms, “thrown into chaos” their orbits, that is, after a certain period of time, their orbits become essentially impossible to predict.
Even if the space mission will allow to hold a very accurate changes to the regulations of Ceres and Vesta, their movements will be unpredictable after 400 thousand years.Moreover, astronomers have found that there is opportunity the collision between these two bodies .Emerged “chaos” will significantly reduce the possibility of predicting changes in Earth’s orbit.As a result, it will be impossible to establish the exact evolution of the eccentricity of Earth’s orbit to beyond a period 60 million years.This means that astronomers can not calculate the parameters of the Earth around the Sun, not only in the future, but in the past, which, in particular, complicates greatly the paleoclimate studing.
