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 ...
However, there are many obstacles to its habitability. The surface temperature averages about -60 degrees Celsius (-80 degrees Fahrenheit). [35] There are no permanent bodies of liquid water on the surface. The atmosphere is thin, and more than 96% of it is toxic carbon dioxide. Its atmospheric pressure is below 1% than that of Earth.
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.
This is a list of cities by average temperature (monthly and yearly). The temperatures listed are averages of the daily highs and lows. Thus, the actual daytime temperature in a given month may be considerably higher than the temperature listed here, depending on how large the difference between daily highs and lows is.
The lower average density and temperature of these objects give them lower index values. Only Titan (a moon of Saturn) is known to hold on to a significant atmosphere despite an overall lower size and density. While Io (a moon of Jupiter) has a low average temperature, surface temperature on the moon varies wildly due to geologic activity. [10]
Mimas, the innermost of the round moons of Saturn and directly interior to Enceladus, is a geologically dead body, even though it should experience stronger tidal forces than Enceladus. This apparent paradox can be explained in part by temperature-dependent properties of water ice (the main constituent of the interiors of Mimas and Enceladus).
Synthetic aperture radar image mosaic of Titan's north polar region. Vid Flumina is a river system (termed Flumen) of liquid methane and ethane on Saturn's moon Titan.It is more than 400 km (249 mi) long and flows into Titan's second largest hydrocarbon sea, Ligeia Mare. [1]
On Saturn, this helium condensation occurs at certain pressures and temperatures when helium does not mix in with the liquid metallic hydrogen present on the planet. [20] Regions on Saturn where helium is insoluble allow the denser helium to form droplets and act as a source of energy, both through the release of latent heat and by descending ...
