Jupiter does not have a solid surface, and the lowest atmospheric layer, the troposphere, smoothly transitions into the planet's fluid interior. [2] This is a result of having temperatures and the pressures well above those of the critical points for hydrogen and helium, meaning that there is no sharp boundary between gas and liquid phases.
Atmospheric super-rotation is a phenomenon where a planet's atmosphere rotates faster than the planet itself. This behavior is observed in the atmospheres of Venus , Titan , Jupiter , and Saturn. Venus exhibits the most extreme super-rotation, with its atmosphere circling the planet in four Earth days, much faster than the planet's own rotation ...
its period is the planet's shortest, at 9h 50m 30.0s--Akbarmohammadzade 09:49, 13 November 2011 (UTC) we are preparing new results for way of explaining reason of Jupiter’s' fast rotation.--Akbarmohammadzade 10:42, 13 November 2011 (UTC) The main reason is conservation of angular momentum.

It's easy for Hubble to take pictures of Jupiter or its moons, but it only gets the chance to capture the planet on cam with three visible Galilean satellites once or twice a decade. That's what ...
Jupiter maintains the moons' orbits via tides they raise on it and thus its rotational energy ultimately powers the system. [1] Saturn's moon Enceladus is similarly thought to have a liquid water ocean beneath its icy crust, due to tidal heating related to its resonance with Dione .
Saturn would later have begun to migrate inwards at a faster rate than Jupiter until the two planets became captured in a 3:2 mean motion resonance at approximately 1.5 AU (220 million km; 140 million mi) from the Sun. [32] This changed the direction of migration, causing them to migrate away from the Sun and out of the inner system to their ...
The planet is about 10% larger than Jupiter, but much hotter because it is 13 times closer to its star than Mercury is to our sun. HD 189733b only takes about two Earth days to complete a single ...
