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 ...
Titan is tidally locked, so the same part of Titan always faces Saturn, and there is no separate "month" cycle. Seasonal change is driven by Saturn's year: it takes Saturn about 29.5 Earth years to orbit the Sun, exposing different amounts of sunlight to Titan's northern and southern hemispheres during different parts of the Saturnian year.
Hot Jupiter A class of extrasolar planets whose characteristics are similar to Jupiter, but that have high surface temperatures because they orbit very close—between approximately 0.015 and 0.5 AU (2.2 × 10 ^ 6 and 74.8 × 10 ^ 6 km)—to their parent stars, whereas Jupiter orbits its parent star (the Sun) at 5.2 AU (780 × 10 ^ 6 km ...

A cold hydrogen-rich gas giant more massive than Jupiter but less than about 500 M E (1.6 M J) will only be slightly larger in volume than Jupiter. [9] For masses above 500 M E, gravity will cause the planet to shrink (see degenerate matter). [9] Kelvin–Helmholtz heating can cause a gas giant to radiate more energy than it receives from its ...

The predicted Bond albedo of a class I planet around a star like the Sun is 0.57, compared with a value of 0.343 for Jupiter [5] and 0.342 for Saturn. [6] The discrepancy can be partially accounted for by taking into account non-equilibrium condensates such as tholins or phosphorus , which are responsible for the coloured clouds in the Jovian ...
LOS ANGELES (AP) - New research suggests there are hot springs bubbling beneath the icy surface of a tiny Saturn moon. If confirmed, it would make the moon Enceladus (ehn-SEHL'-uh-duhs) the only ...
