Abstract

Analysis of the asteroid topography features is of great significance to deep space probe's navigation and selection of landing site. Most analysis and description of deep space topography features are focused on Mars,the moon and other earth-like planets. The asteroids which has great numbers and rich information in the universe are rarely introduced about its topography features in details. Taking Vesta, Eros, Mimas and other detected asteroids as an example, we listed topography surface features of several typical asteroids, improved description parameters of topography features such as craters, and use simulation experiment to generate crater model of Herschel from the Mimas surface. The experimental results show that the method to describe topography features in this paper has great simulational efficiency and practical value.
