The basin of the Sea of Rains can be seen as dark spots with a diameter of 1000 kilometers.
Approximately 3.8 billion years ago the moon was hit by a object with a diameter of 250-300 kilometers, forming on the surface of the satellite so-called ” Sea of Rains.
Scientists suggest that the Sea of Rains has arisen from the impact of the cosmic body that is too large to be called protoplanets.
According to computer models, the size of the object reached a value of 100 kilometers, but new research showed that he was much more. The obtained results explain some features of the relief, which can be observed in the vicinity of the Sea of Rains. On the basis of the scientific work of specialists may say that in the early period of its development, the Solar system was full of protoplanetary, comparable in size to asteroids.
The basin of the Sea of Rains can be seen as dark spots with a diameter of 1000 kilometers. Around the pool are arranged recesses and ridges large enough to see even through small telescopes.
