    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 ...

  4. Lowest temperature recorded on Earth - Wikipedia

    en.wikipedia.org/wiki/Lowest_temperature...

    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 ...

  5. Uranus - Wikipedia

    en.wikipedia.org/wiki/Uranus

    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 ...

    en.wikipedia.org/wiki/TRAPPIST-1

    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).

  7. Climate of Mars - Wikipedia

    en.wikipedia.org/wiki/Climate_of_Mars

    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 ...

  8. Planetary equilibrium temperature - Wikipedia

    [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 ...

  9. Venus - Wikipedia

    [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 ...
