At times when small telescopes don\u2019t show the rings \u2013 when they\u2019re edgewise to us, as they were for a few weeks last March \u2013 Saturn appears as a golden ball, just another distant gas giant world. But the rings make Saturn a showstopper. They draw oohs and aahs through small telescopes. The other gas giants have dim, narrow rings. But Saturn\u2019s rings are bold and beautiful. They\u2019re also weird. Read on to discover 10 weird and wonderful facts about Saturn\u2019s rings.<\/p>\n 1. Saturn\u2019s rings are younger than the oldest dinosaurs.<\/strong> If the earliest dinosaurs, which reigned some 250 million years ago, could manipulate a telescope with their claws, they would have seen a ringless planet. Vahe Peroomian of USC Dornsife College of Letters, Arts and Sciences said: <\/p>\n Saturn\u2019s rings are extremely bright and dust-free, seeming to indicate that they formed anywhere from 10 to 100 million years ago.<\/p>\n<\/blockquote>\n 2. Saturn\u2019s rings are incredibly thin.<\/strong> The rings may look massive, but that\u2019s only true in one direction. The rings span about 170,000 miles (273,000 kilometers) across. Meanwhile, the rings only average about 30 feet (10 meters) in thickness. Most of the particles that make up the rings are less than 1 meter (yard) in size. So the rings may look solid, but, according to NASA, that\u2019s just an: <\/p>\n \u2026 optical illusion on a cosmic scale.<\/p>\n<\/blockquote>\n 3. Saturn\u2019s rings occasionally disappear.<\/strong> Because the rings are so thin, they can seem to disappear from our perspective. Every 14 years or so, from our point of view on Earth, the rings appear edge-on. March 2025 was the last time the rings appeared edge-on. They\u2019ll appear full again in 2032.<\/p>\n 4. But Saturn\u2019s rings really are<\/em> disappearing.<\/strong> And this time it\u2019s not just a trick of perspective. The rings have not always accompanied the planet, and one day they\u2019ll be gone again. That\u2019s because the particles are raining onto Saturn. Scientists call the phenomenon ring rain. And they estimate that in another 100 to 300 million years they\u2019ll be gone. So Saturn\u2019s rings are only a temporary feature. And we\u2019re lucky to be around to see Saturn\u2019s glorious ring system.<\/p>\n 5. Saturn\u2019s E ring is constantly being replenished.<\/strong> Overall, the rings are slowly dissipating through ring rain. But in the meantime, Saturn\u2019s E ring is supplied with a steady stream of material from the moon Enceladus. Enceladus is a fascinating moon that has geysers that shoot icy particles into space. Scientists have even detected organics in those water plumes. The particles shot out by Enceladus drift into orbit and become part of the E ring.<\/p>\n 6. Saturn\u2019s rings are kept in place by shepherd moons.<\/strong> Just like sheep-herding dogs keep their flock in line, Saturn has shepherd moons that keep the ring particles in line. Their gravity \u201cshepherds\u201d the ring particles, keeping them from drifting apart. Moons like Prometheus and Pandora help confine the narrow F ring, for example. <\/p>\n 7. The B ring has mysterious spokes.<\/strong> Visiting spacecraft have witnessed mysterious dark spokes<\/em> on Saturn\u2019s B ring. Voyager saw one that grew over 3,700 miles (6,000 km) in just five minutes. And Cassini saw many spokes, too. Scientists think these spokes are temporary streaks \u2013 both dark and bright \u2013 made of tiny, icy dust particles. When Saturn\u2019s magnetic field interacts with the solar wind, it can electrically charge and suspend the dust particles, causing them to appear as temporary spokes. They last for a few rotations on the rings before fading away. There\u2019s even a spoke season, when Saturn nears the equinox. <\/p>\n 8. The rings are some of the most reflective objects in the solar system.<\/strong> That\u2019s because they\u2019re 99% water ice, so they reflect a lot of sunlight. NASA describes the rings as: <\/p>\n \u2026 a blizzard of water-ice particles mixed with dust and rock fragments.<\/p>\n<\/blockquote>\n 9. The ring particles are moving at a breakneck speed.<\/strong> The serene look of the rings through a telescope is a bit misleading. Those particles of ice and dust are zipping around Saturn at up to 45,000 mph (72,000 km\/h). The rings closest to Saturn orbit fastest, just like the closest planet to the sun \u2013 Mercury \u2013 orbits faster than those farther away. <\/p>\n 10. We\u2019re still not sure how Saturn got its rings.<\/strong> One theory suggests that, 160 million years ago, a large moon of Saturn tore apart and became the planet\u2019s rings. Scientists dubbed this lost moon Chrysalis, for its power to transform from a moon into rings, much as an insect chrysalis produces a butterfly. Another theory says the rings are remnants of the material that formed Saturn\u2019s moons. But this material couldn\u2019t coalesce into a moon because it was inside the Roche limit. And yet another theory suggests meteor impacts shattered a moon, which then became the rings.<\/p>\n Bottom line: Saturn\u2019s rings are a glorious highlight of our solar system. But how long have they existed? And what will happen to them? Plus, how were they born?<\/p>\n Read more: Saturn\u2019s rings: Top tips for beginners<\/p>\n <\/div>\nSaturn\u2019s rings are weird and wonderful<\/h3>\n
