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]
Where Earth's surface has liquid water and supports life, Venus experiences a mean surface temperature of over 400 °C, and a carbon dioxide rich atmosphere with a surface pressure of about 92 times that of Earth at sea-level. Little is known about Venus' surface composition.
For comparison, the hottest planet in the Solar System is Venus, with a temperature of 737 K (464 °C; 867 °F). ... with a temperature comparable to K-type stars.
Akatsuki (あかつき, 暁, "Dawn"), also known as the Venus Climate Orbiter (VCO) and Planet-C, was a Japan Aerospace Exploration Agency (JAXA) space probe tasked with studying the atmosphere of Venus. It was launched aboard an H-IIA 202 rocket on 20 May 2010, [7] but failed to enter orbit around
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]
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.
The surface temperature is at least 35.6 K, with the nitrogen atmosphere in equilibrium with nitrogen ice on Triton's surface. Triton has increased in absolute temperature by 5% since 1989 to 1998. [ 34 ] [ 35 ] A similar rise of temperature on Earth would be equal to about 11 °C (20 °F) increase in temperature in nine years.
The probe confirmed the earlier data on the high Venus surface temperature and pressure (470 degrees Celsius, 90 atmospheres) returned by Venera 7, and also measured the light level as being suitable for surface photography, finding it to be similar to the amount of light on Earth on an overcast day with roughly 1 km visibility.
