From description of impact craters on Venus and crater size‐and‐depth distributions, models are developed that analyze the size‐distribution curve and radar‐bright haloes around fresh craters. The dense Venusian atmosphere has a strong influence on cratering. The estimated age of the surface of the area under study is from 0.5 to 1.0×109 years. The estimated rate of resurfacing during this time interval is about 0.04 to 0.8 cm/106 years. The lithosphere of Venus seems to be sufficiently rigid to sustain craters of 100–140 km diameter and 0.8–2.5 km depth for about 108 years.
