The average surface temperature is about 90.6 K (-182.55 °C, or -296.59 °F). [2] At this temperature water ice has an extremely low vapor pressure, so the atmosphere is nearly free of water vapor. However the methane in the atmosphere causes a substantial greenhouse effect which keeps the surface of Titan at a much higher temperature than ...
Saturn is the sixth planet from the Sun and the second largest in the Solar System, after Jupiter. It is a gas giant, with an average radius of about nine times that of Earth. [27] [28] It has an eighth the average density of Earth, but is over 95 times more massive.
Projected global surface temperature changes relative to 1850–1900, based on CMIP6 multi-model mean changes. The IPCC Sixth Assessment Report defines global mean surface temperature (GMST) as the "estimated global average of near-surface air temperatures over land and sea ice, and sea surface temperature (SST) over ice-free ocean regions, with changes normally expressed as departures from a ...
The average temperature of the atmosphere at Earth ... (Jupiter and Saturn), ... with the global average surface temperatures being 1.1 °C higher in the 2011 ...
25 kK, mean temperature of the universe 10,000 years after the Big Bang; 26 kK on the white dwarf Sirius B; 28 kK in record cationic lightning over Earth; 29 kK on surface of Alnitak (easternmost star of Orion's belt) 4–8–40–160 kK [clarification needed] on white dwarfs; 30–400 kK on a planetary nebula's asymptotic giant helium star
NASA's Cassini spacecraft, which explored Saturn and its icy moons, including the majestic Titan, ended its mission with a death plunge into the giant ringed planet in 2017. Cassini's radar ...
Because it reflects so much sunlight, its surface only reaches a mean noon temperature of −198 °C (−324 °F), somewhat colder than other Saturnian satellites. [ 12 ] Observations during three flybys on February 17, March 9, and July 14, 2005, revealed Enceladus's surface features in much greater detail than the Voyager 2 observations.
[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 ...
