Orbiting in the plane of Saturn's rings, Dione and the other icy saturnian moons have a perpetual ringside view of the gorgeous gas giant planet. Of course, while passing through the ring plane the Cassini spacecraft also shares their stunning perspective. The rings themselves can be seen slicing across the bottom of this Cassini snapshot. Remarkably thin, the bright rings still cast arcing shadows across the planet's cloud tops. Pale Dione, in the foreground, is about 1,100 kilometers across and orbits over 300,000 kilometers from the visible outer edge of the A ring.

I'll give out a free membership to the SE Chapter to anyone who can tell me what other planet in our Solar System "USED" to have rings, but no longer does. This is past tense, so remember that.

Cool pic Mark, i will guess later today!!!!!!!!!!!!!!!!!!!!!!

Just off the top of my head but Uranus? No wait...that big bastard still does have a small one.

But then again...all planets used to have rings. Until those rings solidified into a recognizable satellite. Correct?

very good, but not totally correct. Jupiter has moons, but never had rings. However your logic will lead you to the correct answer.

Crap...this is turning out to be harder than imagined. We know that all of the Jovial Planets have rings. Pluto couldnt hold on to spit if it weren't for Charon. The only thing I can remember is Venus. I know there are still some circles that claim that she may still have a satellite. But I don't remember anything about rings. Mars? I would think that Mars would be able to hold on to it. Unless Phobos and Diemos ran into em all. Ugh...I guess I'll keep looking.

that is a very cool pic

AWesome pic!!:Beer :Beer

what exactly are the rings ??? are they solid???? lets just say we could travel to one and they had a grivitational pull could we walk on it??

they are giant rocks orbiting for so long, they turned into rings.
