5 Fascinating Facts About Saturn’s Rings

The rings of our favorite gas giant are actually named in alphabetical order based on the time they were discovered, to date the rings have only reached G but working from the planet out, the letters go D, C, B, A, F, G, E with the D ring being a very faint ring and the E ring capable of fitting almost 2 billion Mars’. Most of these are very close together, this is with one exception, B and A, these rings are 2,920 miles (4,700 km) apart and is down to a phenomenon known as the Cassini Division.

For such enormous rings they’re relatively small, as mentioned before the largest ring span 200 times that of the diameter of Saturn but the average ring is only around 100 yards thick. This ultra-thin nature is caused by the particles striking together and dropping down as those particles at the top tend to have a lot more energy than those closer to the ring’s center. As these particles crash the energy is lost and they drop lower into the ring giving it a thinner range.

When Saturn’s rings were first discovered in 1610 by every astronomer’s old friend Galileo, he thought they looked more like ears or handles than rings. It took almost 50 years for the real discovery of Saturn to become apparent when in 1656 Christiaan Huygens discovered the ears weren’t in fact arm-like but circled the planet in a thin ring. As the years went on, we learned more and more about our gaseous friend, including the fact that the ‘thin ring’ mentioned was actually a range of rings.

Saturn’s rings were obviously not enough of a scientific mystery for the powers that be, because they decided to create a phenomenon known as “Spokes”. These Spokes are strange markings that appear across the rings in minutes and last a few hours at most before disappearing. They were first recognized by the Voyager Spacecraft and again in 1981 by Voyager 2. The markings themselves are stopped from forming if sunlight hits the rings, a feature that baffled the Cassini craft in 2004 as they were photographing the rings when they were in the sun.

So there we have it, from spokes to spacing, there really is a plethora of interesting facts about the wondrous rusty colored rings surrounding Saturn, and that’s just the information we know, I can guarantee in the next 50 years there will be plenty more facts and figures released to us mere public that’ll amuse and bemuse us further.
