Saturn

What's up with those rings

http://saturn.jpl.nasa.gov/home/index.cfm
I've been interested in astronomy for some time now. I even built my own telescope, a 8in. Dobsonian. So I've been following the progress of the Cassini-Huygens craft that has been circling Saturn for a while. I can't get enought of the pictures that are sent back and then posted for all to see.

They clean up a few and put captions on them but I really like going through the raw images. I've read that "The particles in Saturn's rings are composed primarily of water ice and range from microns to meters in size" . So is there a thickness to these rings?

If you take a look at a picture like this one (I hope this works)

It's not quite edge on but close, and the look like they're pretty thin. I do realize that Saturn is rather large, it would be a tight fit between the Earth and the Moon, so it may be that they have a significant thickness but compared to the planet it looks rather small.

The rings are only a few hundred meters thick (100-300m). That razor thin edge you 'see' is a trick of the massive scale...

Cant see the picture

If earth is basketball-sized, the air is just paper-thick sheet covering the basketball.

It's just a matter of scale. The rings IS extremely thin, when compared to the scale of Saturn itself.

Thanks for the response. About 5 min. after I posted my message. I came across this:

How thick are the main rings?

They're extremely thin compared to their breadth, no more than 100 meters (about 300 feet) thick. To get an idea of their proportions, imagine a ring as thin as a sheet of paper and about 3 km (2 miles) in diameter.

It's amazing what happens when you locate a FAQ link at the very bottom of a page. ; )

Impressive!
