| Abstract: | Up to now,there have been some 5 billion years for the whole evolutionary history of the solar system,in which catastrophic events happened on relatively short time-scales and possibly played a decisive role in formation and evolution of some celestial objects,such as planets,our Moon and other satellites,asteroids and planetary rings. |
