Planetary Ring Systems 

Best Saturn video ever!

Awesome video. Great content You should have millions of views on this.

Very cool video thanks for sharing!:)

I swear that backlit photo of Saturn was so beautiful but yo, when I saw earth from the back, I started yelling like a sports fan. GO BLUES!!!

What a nice video. Thank you!

Awesome!!! How can there be so few views???

Outstanding video. I never knew there was potential for anything other that our gas and ice giants to have rings. The rings around certain asteroids was really interesting.

Galileo wrote: "Has Saturn eaten his children?" when he didn't spot them.

Really engaging video! It includes details I've never heard or seen in other videos!

Interesting and beautiful video❤❤❤

I just had to leave a comment! Awesome content!

This video probably should be updated given the results of the Cassini mission's grand finale For instance those small moons are denser rockier bits which have accreted or are accreting ring material in what seems like it might be a far more efficient process than what we had thought What blew my mind is that we now think that the rings as well as the embedded and accreting shepherd moons and the planets mid sized moons Mimas Enceladus Tethys (and its two Trojan companions at its L4 and L5 Lagrange points) Dione Rhea and perhaps even Titan itself are young no older than a billion years old at most with the moons having formed through accretion of ring material around rockier fragments of the unfortunate parent body (as rockier material possessed greater integrity to hold together against tidal forces). At the current rate of particles infalling into Saturn, the grand rings of Saturn will be gone within 100 million years meaning we are very privileged to be able to see them during their brief existence. Someday they will become diffuse fossil rings not dissimilar to the other giant planets. Regarding Mars there is some evidence to suggest it might be even more complicated as there are a number of unusual characteristics suggesting they likely both accreted from the same ring of material including tier chemical composition most closely matching that of Mars itself. Also interesting are a number of strange craters found in the orbital plane of Phobos and Deimos including one especially strange "orca" shaped feature that could be a crater from a moon that crashed into Mars in a unusual way though this hypothesis remains to be tested. The point is Phobos might not be the first moon to crash into Mars rather the last of a number of doomed moons that have rejoined the red planet. It is also interesting to note that considerable tidal stress fractures are visible on Phobos so the moon's destruction is already well in progress. I have to wonder if an object was dropped from the Mars facing side of the moon would it fall up or down? If a number of such objects were dropped between Mars and Phobos at what point would they fall one way or another (i.e. what does the gravity field around a near tidally disrupted body look like)

I hope we send a spacecraft to Chiron within my lifetime.

Every time I look at Saturn's rings I wonder what songs it plays

If a meteor went through the rings and punched a hole, how long it will take for the rings to return to their original form? Will they at all?

hmm People living on Mars when Phobos already disintegrated pass the Roche Limit is probably a bad idea. The atmospheric drag alone (even without Saturn's electromagnetic method of draining its rings) might be enough to cause those poor Phobonian fragments to one by one come crashing down on our poor Martian future colonies. :p

Are Saturn's rings stable?

I think “Chiron” should be pronounced as “Kai-Ron”

What about the rings of Saturn's major moon Rhea?

Hello

Uranus has 27 moons, not 14.

Oh My Drool! WHAT IS GOING ON!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! MY RINGS ARE MADE OF FOGS OF DUST
