Saturn

Type: Gas giant planet
Mass: 5.7 × 10^26 kg
Position in the Solar System: 6
Distance from the Sun: 1.4 billion km

Saturn is the second largest planet in the Solar System, both by size and mass. It is famous for its spectacular ring system, composed primarily of ice, rock, and dust. With its perfect geometry and ever-changing patterns, Saturn is one of the most fascinating objects in the night sky to photograph.

Fun fact: Saturn's famous rings aren't eternal. They are slowly disintegrating under the influence of gravity and the planet's magnetic field. At this rate, they could disappear completely within 100 million years—the blink of an eye on a cosmic scale.
