Venus has a solid surface covered in dome-like volcanoes, rifts, and mountains, with expansive volcanic plains and vast, ridged plateaus.
Three Views of the Structure of Venus - NASA Solar System …
These three perspective images show the structure of Venus at the surface, in the crust and in the mantle. The upper plane shows surface features seen by Magellan's imaging radar "draped" over a three-dimensional representation of surface topography seen by the altimeter.
Magellan Summary Sheet - NASA Solar System Exploration
Venus has a surface temperature of about 470 degrees Celsius (about 900 degrees Fahrenheit); the atmsopheric pressure at the surface is 90 times greater than Earth's. Venus's atmosphere is nearly devoid of water, made up of 97 percent carbon dioxide; its …

1993年3月10日 · The map depicts the shapes of Venusian mountains, canyons and other surface features with higher resolution than has ever been seen before on a global scale.
30 Years Ago: Magellan Off to Map Venus - NASA Solar System …
2019年5月6日 · Volcanic features are very common on Venus, making up the majority of surface formations including vast lava plains, lava domes, and large shield volcanoes. Evidence of meteorite impacts is limited, indicating that the surface of Venus is relatively young, on the order of 800 million years old.
Magellan Mission at a Glance - NASA Solar System Exploration
The surface of Venus is mostly covered by volcanic materials. Volcanic surface features, such as vast lava plains, fields of small lava domes, and large shield volcanoes are common. There are few impact craters on Venus, suggesting that the surface is, in general, geologically young - less than 800 million years old.
