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 ...
It is the moon with the highest volcanic activity in the Solar System, as a result of the tidal forces from the planet and its oval orbit around it. Even so, the surface is still cold: -143 Cº. The atmosphere is 200 times lighter than Earth's atmosphere, the proximity of Jupiter gives a lot of radiation, and it is completely devoid of water.
Saturn and Jupiter may be gas giants now, but according to some experts, they were once nothing more than tiny pebbles, and a recent study supports that assertion. The prevailing theory is that ...
Jupiter has powerful storms, often accompanied by lightning strikes. The storms are a result of moist convection in the atmosphere connected to the evaporation and condensation of water. They are sites of strong upward motion of the air, which leads to the formation of bright and dense clouds. The storms form mainly in belt regions.
In January and February, look for Venus and Saturn in the southwestern sky and Jupiter and Mars toward the southeast. These planets will be spread out across a long arc but two unseen planets will ...
Hot & Wet (Spring/Air) Cold & Dry (Autumn/Earth) Gemini Air Hot & Wet ... Jupiter for Space, Saturn for Air, Mars for Fire, Mercury for Earth, and Venus for Water.
The holiday season holds a special gift, as skygazers on Earth will be treated to a great conjunction of the planets Jupiter and Saturn. Using binoculars or a backyard telescope, it will not only ...
