Surface temperature; Highest Lowest Highest Lowest Highest Lowest Sun: N/A 5,000,000 K In a solar flare [33] 1240 K In a sunspot [34] Mercury: 3 kilometres (1.9 mi) Caloris Montes, northwest Caloris Basin rim mountains [35] [36] 723 K Dayside of Mercury [37] 89 K Permanently shaded polar craters [38] Venus: 11 kilometres (6.8 mi) Maxwell Montes ...
Surface gravity (log g) 1.70 ± 0.05 [8 ... Some observers may have perceived Canopus as yellow-tinged because it is low in the sky and hence subject to atmospheric ...
The temperature announced reflects that of the ice surface, while the Vostok readings measured the air above the ice, and so the two are not directly comparable. More recent work [5] shows many locations in the high Antarctic where surface temperatures drop to approximately −98 °C (−144 °F; 175 K). Due to the very strong temperature ...
The lowest temperature recorded in Uranus's tropopause is 49 K (−224.2 °C; −371.5 °F), making Uranus the coldest planet in the Solar System. [ 18 ] [ 95 ] One of the hypotheses for this discrepancy suggests the Earth-sized impactor theorised to be behind Uranus's axial tilt left the planet with a depleted core temperature, as the impact ...
TRAPPIST-1 is a cool red dwarf star [c] with seven known exoplanets.It lies in the constellation Aquarius about 40.66 light-years away from Earth, and has a surface temperature of about 2,566 K (2,290 °C; 4,160 °F).
Orbital measurements showed that this dust storm reduced the average temperature of the surface and raised the temperature of the atmosphere of Mars by 30 K. [31] The low density of the Martian atmosphere means that winds of 18 to 22 m/s (65 to 79 km/h) are needed to lift dust from the surface, but since Mars is so dry, the dust can stay in the ...
[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 our lower atmosphere. [5] [4] The surface temperatures of such planets are more accurately estimated by modeling thermal radiation transport through the ...
[90] [91] This makes the Venusian surface hotter than Mercury's, which has a minimum surface temperature of 53 K (−220 °C; −364 °F) and maximum surface temperature of 700 K (427 °C; 801 °F), [92] [93] even though Venus is nearly twice Mercury's distance from the Sun and thus receives only 25% of Mercury's solar irradiance, of 2,600 W/m ...
