Saturn

Saturn is the second-largest planet in the Solar System and is immediately recognizable because of its broad ring system.

Although other giant planets also have rings, Saturn's are especially large and visible, making the planet one of the clearest examples of material orbiting another world.

Saturn's rings are made of enormous numbers of particles ranging from tiny grains to much larger pieces, with water ice making up much of the visible material.

The rings are divided into bands and gaps shaped by gravity, collisions, and interactions with Saturn's moons.

Saturn is much farther from the Sun than Earth, so it follows a much larger orbital path and takes about 29 Earth years to complete one trip around the Sun.

Its slow movement in the TransitSatellite Solar System map gives users a useful comparison with Mercury, Venus, Earth, and Mars.

Saturn has a large family of moons, including Titan, a world with a thick atmosphere, and Enceladus, which ejects material from an ocean beneath its icy surface.

The planet, rings, and moons together form a miniature orbital system that helps demonstrate how gravity organizes many objects around a central body.

Saturn connects naturally with TransitSatellite's focus on tracking and motion because its ring particles and moons all follow paths governed by gravity.

The planet also provides an important outer-Solar-System target for the Pro Planet Visibility feature.
