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 has a hot interior, reaching 11,700 °C (21,100 °F) at its core, and radiates 2.5 times more energy into space than it receives from the Sun. Jupiter's thermal energy is generated by the Kelvin–Helmholtz mechanism of slow gravitational compression; but such a process alone may not be sufficient to explain heat production for Saturn ...
Consequently, its surface temperature at noon reaches only −198 °C (75.1 K; −324.4 °F), far colder than a light-absorbing body would be. Despite its small size, Enceladus has a wide variety of surface features, ranging from old, heavily cratered regions to young, tectonically deformed terrain .

Mosaic of three Huygens images of channel system on Titan. The possibility of hydrocarbon seas on Titan was first suggested based on Voyager 1 and 2 data that showed Titan to have a thick atmosphere of approximately the correct temperature and composition to support them, but direct evidence was not obtained until 1995 when data from Hubble and other observations suggested the existence of ...
If you could somehow make it through all of that, then a blistering hot core made of iron and nickel awaits you at the planet’s center—along with a surprise, as scientists have yet to discover ...
Its surface temperature is on average 75 K (−198.2 °C). Cassini 's closeup of Phoebe from 13 June 2004; the crater Euphemus is at top center. Most of Saturn's inner moons have very bright surfaces, but Phoebe's albedo is much lower in comparison (0.100 ± 0.005), though relatively bright compared to other irregular moons with measured ...
A deep ocean exists beneath the icy, cratered surface of Saturn’s moon Mimas, according to a new analysis of data from NASA’s Cassini mission.
