Our models show that, for a large and physically reasonable region of parameter space, this typically leads to the formation of one to four gas giants between 5 and 15 astronomical units from the Sun, in agreement with the observed structure of the Solar System....
The atmospheric motions we see on these planets are fundamentally different from those on the terrestrial planets. The giants spin faster, and their rapid rotation tends to smear out of the circulation into horizontal (east-west) patterns parallel to the equator. In addition, there is no solid ...

You see, most of the outer accretion disk would have been gas. We believe solid particles probably made up just one percent of the outer accretion disk.So this theory suggests that large planets, the gas giants, uh, they develop from large clumps of mostly gas and some dust in an accre...
Gas giants are large planets that contain more than 10 times the mass of Earth, they are also known as the Jovian or Outer Planets. Their compositions are mostly gases, such as hydrogen, and small amounts of rocky material (mostly at their cores). The four gas giants in our solar ...

But what about those gas planets in the outer solar system, in the outer accretion disk? Well, the first theory says the accretion process was similar to the one that formed the rocky planets, with some key differences. Remember the gas giants are farther from the Sun, where temperatures ...
It is widely held that the first step in forming the gas giant planets, such as Jupiter and Saturn, is to form solid `cores' of roughly 10 M$_\oplus$. Getting the cores to form before the solar nebula dissipates ($\sim\!1-10\,$Myr) has been a major chall
gas giant (redirected fromGas planet) Thesaurus gas giant n. A large planet having a thick gaseous atmosphere but no solid surface due to a low abundance of rock or other solid material. Jupiter, Saturn, Uranus, and Neptune are gas giants. ...
