The planet may have had a major global resurfacing event about 500 million years ago, [1] from what scientists can tell from the density of impact craters on the surface. Venus has an atmosphere rich in carbon dioxide, with a pressure that is 90 times that of Earth's atmosphere. There are over 80,000 [2] volcanoes on Venus detected through ...
Global radar map of the surface of Venus. The surface of Venus is dominated by geologic features that include volcanoes, large impact craters, and aeolian erosion and sedimentation landforms. Venus has a topography reflecting its single, strong crustal plate, with a unimodal elevation distribution (over 90% of the surface lies within an ...
Cleopatra (initially called Cleopatra Patera [2]) is an impact crater on Venus, in Maxwell Montes. Cleopatra is a double-ring impact basin about 100 kilometers (62 mi) in diameter and 2.5 kilometers (1.6 mi) deep. A steep-walled, winding channel a few kilometers wide ( Anuket Vallis) breaks through the rough terrain surrounding the crater rim.
Venus, the second planet from the Sun, is classified as a terrestrial planet. It is sometimes called Earth's "sister planet" due to their similar size, gravity, and bulk composition (Venus is both the closest planet to Earth and the planet closest in size to Earth). The surface of Venus is covered by a dense atmosphere and presents clear ...
Lunar: 1,624 craters (31.2%) Venusian: 900 craters (17.3%) Mercurian: 397 craters (7.6%) Martian: 1,092 craters (21.0%) Others: 1,198 craters (23.0%) Distribution of named craters in the Solar System as of 2017. [a] This is a list of craters on Venus, named by the International Astronomical Union's (IAU) Working Group for Planetary System Nomenclature. All craters on Venus are named after ...
Stefania is a crater on Venus in the northern Sedna Planitia.With a diameter of 11 kilometers (6.8 mi) it is one of the smaller craters on Venus. Because many small meteoroids disintegrate during their passage through the dense atmosphere, there is an absence of craters smaller than 3 kilometers (1.9 mi) in diameter, and even craters smaller than 25 kilometers (16 mi) are relatively scarce.
Venus has several times as many volcanoes as Earth, and it has 167 large volcanoes that are over 100 km (60 mi) across. The only volcanic complex of this size on Earth is the Big Island of Hawaii. [ 46 ] : 154 More than 85,000 volcanoes on Venus were identified and mapped.
The hemispheric view of Venus, as revealed by more than a decade of radar investigations culminating in the 1990–1994 Magellan mission, is centered at 180 degrees east longitude. The geology of Venus is the scientific study of the surface, crust, and interior of the planet Venus. Within the Solar System, it is the one nearest to Earth and ...
