Abstract: According to the expedition of spacecraft for lunar crust, it is found that the surface structure on lunar farside quite differs from that on the nearside. According to the lunar figure model (CE-1), the lunar shape center is deviated 1117 m from the lunar mass center. The lunar dichotomy structure and the deviation of the shape center are very specific in solar system, and it must have a common evolutionary reason. The author suggested that after the Moon formed the synchronous rotation in about 3.5 billion years ago, because the Earth’s strong gravity and the Moon was near to the Earth, only a litter meteorite fell down to the nearside of the Moon, and the most meteorite fell down to the farside of the Moon, and formed a thick cover layer. According to the deviation of the lunar shape center from the mass center, we may estimate that the average thickness of the cover layer is about two thousand metres, and the mass of the cover layer is only about 1.1 × 10−4 of the lunar mass.
