The light planets or gas giants They are located on the outside of the Solar System.
They are planets consisting basically of hydrogen and helium, a reflection of the composition of the primitive solar nebula.
These gas giants have important meteorological activities and gravitational processes, with a small core and a large mass of gas in permanent convection.
Jupiter, Saturn, Uranus, and Neptune are known as the Jovian planets, that is, relative to Jupiter. They are gigantic compared to Earth and have a gaseous nature like Jupiter's. Jovian planets are considered gas giants, although some have a solid center.
The great planets, Jupiter and Saturn, have satellite systems that, in a way, are miniature models of the Solar System. Although they do not have thermonuclear energy sources, they continue to release gravitational energy in an amount greater than the solar radiation they receive.
Another common feature is to have rings formed by small particles in orbits closer than those of their satellites.
