Topographic Map of Venus. There are three types of topography on Venus Highlands with elevation greater than 3 km, cover about 10% of the surface; Deposition plains with elevations around 0 to 2 km, cover more than 50% of the surface; Lowlands (accumulation of eroded highlands) with negative elevation, cover the rest of the surface
The surface of Venus is comparatively flat. When 93% of the topography was mapped by Pioneer Venus Orbiter, scientists found that the total distance from the lowest point to the highest point on the entire surface was about 13 kilometres (8.1 mi), about the same as the vertical distance between the Earth's ocean floor and the higher summits of the Himalayas.
Coronae on Venus differ in the location of topographic uplift, and have been characterized as such. Topographic uplift may occur in the depression, the rim, the outer rim, or a combination of these locations. A collapsing coronae coupled with extensional stressing may result in rifting, creating a chasmata region. [9] [11]
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 evidence of former violent volcanic activity.
Color-coded elevation map, showing the elevated terrae "continents" in yellow: Ishtar Terra at the top. Topographic radar image view of Venus, with Ishtar Terra near center. Ishtar Terra / ˈ ɪ ʃ t ɑːr ˈ t ɛr ə / [1] is the second largest of the three continental terrae regions on the planet Venus, the others being Aphrodite Terra and ...
Global topographic map of Venus, with all probe landings marked Venus is the place of the first interplanetary human presence, mediated through robotic missions, with the first successful landings on another planet and extraterrestrial body other than the Moon.
In 1978, the space probe Pioneer Venus 1 went into orbit around Venus for the purpose of making radar observations of the Venusian surface. These observations made possible the creation of the first topographic map of the surface of Venus, and confirmed that a point within Maxwell Montes is the highest point above the average level of the ...
The spacecraft's telecom system will be used to map gravity strength at Venus' surface, providing a uniform resolution of better than 160 km. [16] [23] The data will provide an estimate of Venus' core size and information about topographic features that lie underneath the planet's surface. [24] [25]
