Sledstviya stolknoveniya, porodivshego Lunu: traektorii oskolkov

The Moon was formed as a result of the Giant collision (Big Splash) of Proto-Earth with a planet called Theia. The debris of this event, scattered far from the Earth, return to a narrow region of the Solar System near the point of Giant Collision. Since the Earth itself also returns to this point every year, the falling of debris on our planet during the first thousand years after the collision is quite likely. A heavy early bombardment of the Earth and the Moon delivered to the planet water and those gases that were eliminated via a very strong heating during the Giant collision. This is the way of the Earthв„ўs atmosphere and ocean formation. We have clarified many details of these events; in particular, we have estimated the probability of debrisfalling not only on the Earth, but also on Mars and Venus. The article presents calculations of various trajectories of debris formed in the Collision,obtained by numerically solving the three-body problem. In prospect, we are going to discuss the evolution of the debris in different orbits and consequences of their falls to the Earth.
