Saturn
The planet with rings.
Characteristics
Saturn is one of the four gaseous planets, it is the 2nd largest planet in the solar system behind Jupiter.
It takes him 30 years to complete a full circle around the Sun.
Elle est connue pour ses anneaux constitués de glace et de poussières.
Flattening
Saturn does not have a perfectly spherical shape, it is flattened at the poles. It is the most flat planet in the solar system.
Composition
Saturn is composed mainly of hydrogen and helium, like Jupiter.
Magnetosphere
The intensity of Saturn's magnetic field is about 20 μT, so it is weaker than that of Earth.
Moons
With 274 known natural satelittes, Saturn is the planet that has the most.
Seven of these moons took on a spherical shape under the effect of their own gravity: Titan, Rhea, Iapetus, Dione, Tethys, Enceladus and Mimas. With Hyperion (which does not have a spherical shape) they form the 'major' moons.
Rings
Saturn’s rings are not continuous but consist of countless particles whose size varies.
These particles are composed of about 95% pure water ice.
They are placed about 75,000 km away from the planet’s equator and extend up to 137,000 km.
