The surfaces of planets and moons are not pristine. The surfaces of planets possessing atmospheres, such as Mars, are modified by various processes, such as asteroid impacts, groundwater movement, ultraviolet radiation, low atmospheric pressures, fluctuating temperatures, and windblown dust. Even planetary bodies which do not have an atmosphere, such as the Moon, are subject to processes that can affect their surface (because of the lack of a protective atmosphere). These processes include micrometeorite and asteroid impacts, irradiation by energetic photons ranging from gamma rays to ultraviolet, and solar wind irradiation and implantation of various ions.

行星和卫星的表面并不是原始的。拥有大气层的行星（如火星）的表面会受到各种过程的影响，如小行星撞击、地下水运动、紫外线辐射、低气压、温度波动和风沙。即使是没有大气层的行星，如月球，也会受到影响其表面的过程的影响（因为缺乏保护性的大气层）。这些过程包括微陨石和小行星撞击、从伽马射线到紫外线的高能光子辐照、太阳风辐照和各种离子注入。
