The atmosphere is divided into a number of sections depending on altitude. The densest part of the atmosphere, the troposphere , begins at the surface and extends upwards to 65 km. The winds are slow near the surface, [ 1 ] but at the top of the troposphere the temperature and pressure reaches Earth-like levels and clouds pick up speed to 100 m ...
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.
Conditions perhaps favourable for life on Venus have been identified at its cloud layers. Venus may have had liquid surface water early in its history with a habitable environment, [24] [25] before a runaway greenhouse effect evaporated any water and turned Venus into its present state. [26] [27] [28] The rotation of Venus has been slowed and ...
Today's Venus can be described as hellish: there is almost no water vapor, the carbon dioxide atmosphere is 90 times as thick as that on Earth and temperatures can reach a scorching 864 degrees.
"Venus now has surface conditions that are extreme compared to Earth, with an atmospheric pressure 90 times greater, surface temperatures soaring to around 465°C (869°F), and a toxic atmosphere ...
Searches for more satellites have been unsuccessful, putting the maximum radius of any other satellites at 90 m (100 yd). [4] Jupiter has 95 moons with known orbits; 72 of them have received permanent designations, and 57 have been named. Its eight regular moons are grouped into the planet-sized Galilean moons and the far smaller Amalthea group ...
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 elevation of -1.0 and 2.5 km) [1] that preserves geologic structures for long periods of time.
Terrestrial planets are substantially different from the giant planets, which might not have solid surfaces and are composed mostly of some combination of hydrogen, helium, and water existing in various physical states. Terrestrial planets have a compact, rocky surfaces, and Venus, Earth, and Mars each also has an atmosphere. Their size, radius ...
