Note that the meridional circulation is much lower than the zonal circulation, which transports heat between the day and night sides of the planet. All winds on Venus are ultimately driven by convection. [3] Hot air rises in the equatorial zone, where solar heating is concentrated and flows to the poles.
For example, Venus has an effective temperature of approximately 226 K (−47 °C; −53 °F), but a surface temperature of 740 K (467 °C; 872 °F). [ 13 ] [ 14 ] Similarly, Earth has an effective temperature of 255 K (−18 °C; −1 °F), [ 14 ] but a surface temperature of about 288 K (15 °C; 59 °F) [ 15 ] due to the greenhouse effect in ...
Being closer to the Sun, Venus receives about 1.9 times more sunlight than Earth, but due to the thick atmosphere, only about 20% of the light reaches the surface. [6] [7] Color images taken by the Soviet Venera probes suggest that the sky on Venus is orange. [8] If the Sun could be seen from Venus's surface, the time from one sunrise to the ...
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 exoplanets irradiated by a nearby star and greater than 2,000 K (1,730 °C; 3,140 °F) for self-luminous exoplanets.
A NASA spacecraft has captured never-before-seen images of Venus, providing stunning views of the hellishly hot surface of the second rock from the sun. Dark side of Venus revealed in new NASA ...
Venus is a primary feature of the night sky, and so has been of remarkable importance in mythology, astrology and fiction throughout history and in different cultures. The eight-pointed star a symbol used in some cultures for Venus, and sometimes combined into a star and crescent arrangement.
Stratospheric zonal winds on Titan were observed on the order of 100-200 m s −1, [5] faster than the highest zonal winds on Earth at ~60-70 m s −1. Questions on the effect of obliquity in super-rotation on Titan is often compared to Venus, as they share similar centrifugal accelerations to achieve dynamic balance.
Venus' oceans may have boiled away in a runaway greenhouse effect. A runaway greenhouse effect involving carbon dioxide and water vapor likely occurred on Venus. [22] In this scenario, early Venus may have had a global ocean if the outgoing thermal radiation was below the Simpson–Nakajima limit but above the moist greenhouse limit. [2]
