WebMar 22, 2010 · This computer-generated view of the surface of Venus was created from radar images taken during NASA’s Magellan mission during the 1990s. The images suggest that the Venus surface evolves through a periodic resurfacing process, possibly caused by volcanic activity. Credits Image: NASA Jet Propulsion Laboratory WebThe diameter of Venus is 12,103.6 km (7,520.8 mi)—only 638.4 km (396.7 mi) less than Earth's—and its mass is 81.5% of Earth's. Conditions on the Venusian surface differ radically from those on Earth because its dense atmosphere is 96.5% carbon dioxide, with most of the remaining 3.5% being nitrogen. [28]

WebApr 14, 2024 · Hahn took the highest-resolution imagery available of the Venusian surface — that gathered by NASA’s Magellan spacecraft 30 years ago — loaded it into mapping software like that used by engineers and urban planners on Earth. Then she set out to map every single volcano visible in the grainy, black-and-white images by hand. WebJan 1, 2011 · Roughly 90% of the surface appears to be solidified basalt lava. More than 1000 volcanoes, with diameters in excess of 12 miles, cover the surface of Venus. There are two datasets that display information about the topography of Venus.
