Topped only by Jupiter, Saturn is the second-biggest planet in our Solar System. With a diameter measuring roughly four-and-a-half times greater than Earth’s, Saturn is designated a gas giant. Yet its most notable characteristic is perhaps its ring system, which is the most considerable in the whole Solar System. As research has recently suggested, however, these rings might not last forever.
Composed of ice and rock particles – some large, others minuscule – Saturn’s ring system is about 170,000 miles in diameter. Its average thickness, on the other hand, measures just approximately 30 feet. So given these specific features, it’s generally been questioned whether or not the system would endure over time.
