Lunar Crater Spatial Distribution for Each Surface Model Age
Abstract
A numerous impact craters which exist on the surface of bodies in the solar system, generally are distributed at spatially random. However, spatial distribution of the craters on the moon attaining same rotation and revolution periods is affected to have a bias that lunar crater size-frequency distribution at the leading side is larger than that of other side. The observational evidence of a biased crater spatial distribution due to the synchronized rotation and revolution were reported by Morota et al. (2005) and Werner and Medvedev (2010), that showed that the rayed craters which has formed after 1.1 Ga reveal the synchronized rotation and revolution. In this study, spatial distribution of lunar craters based on the Voronoi tessellation which can be regarded a Voronoi cell as a territory of each crater corresponding to a generator was conducted for each lunar surface model age (Wilhelms et al., 1987). The result of spatial distribution for each model age supports an interpretation that the synchronized rotation and revolution of the moon started at least in the Nectarian system.
