The downwelling over the nightside causes adiabatic heating of the air, which forms a warm layer in the nightside mesosphere at the altitudes 90–120 km. [3] [2] The temperature of this layer—230 K (−43 °C)—is far higher than the typical temperature found in the nightside thermosphere—100 K (−173 °C). [2]
At the surface it has a mean temperature of 737 K (464 °C; 867 °F) and a pressure 92 times that of Earth's at sea level. These extreme conditions compress carbon dioxide into a supercritical state at Venus's surface. Internally, Venus has a core, mantle, and crust.
This is a list of the hottest exoplanets so far discovered, specifically those with temperatures greater than 2,500 K (2,230 °C; 4,040 °F). For comparison, the hottest planet in the Solar System is Venus , with a temperature of 737 K (464 °C; 867 °F).
This bizarro world, with surface temperatures about 900 degrees Fahrenheit, Long ago Venus was nicknamed Earth's twin, a world roughly the same size as our home planet and the nearest neighbor in ...
The very first visible-light images of Venus' surface from space have been captured by NASA's Parker Solar Probe, and it could help researchers piece together the mysteries of the distant planet.
"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 ...
The surface conditions on Venus are more extreme than on Earth, with temperatures ranging from 453 to 473 °C and pressures of 95 bar. [3] Venus lacks water, which makes crustal rock stronger and helps preserve surface features. The features observed provide evidence for the geological processes at work.
If these surface minerals were fully converted and saturated, then the atmospheric pressure would decline and the planet would cool somewhat. One of the possible end states modelled by Bullock and Grinspoon was an atmosphere of 43 bars (42 atm; 620 psi) and a surface temperature of 400 K (127 °C; 260 °F).
