Consequences of the Collision that Spawned Moon: Evolution of Debris in the Orbits of the Solar System

We continue to describe the debris of the Moon formation, which after the Giant collision appeared to be in the orbits of the Solar System. In the previous article, their trajectories were considered; in this one we will talk about the evolution of these fragments. The radiation cooling resulted in quick decrease of their surface temperatures to a level acceptable for water vapor condensation. During multiple passes of debris through the point of the Giant collision, they also came into collisions with each other, which caused ice sublimation and local heating. These processes are possibly responsible for the formation of those granulation structures that are observed in chondrites.
