The rings of Saturn may be vast in diameter, but they are likely only a few meters thick… maybe a dozen in some places. The rings are made up of bits of water ice, which, based on radio measurements, appear to range from a few centimeters to several meters in diameter. There are as yet no direct photos showing the makeup of the rings; no spacecraft has come anywhere near close enough for that. So about the best there is is artwork, such as this older piece from JPL:

If this is accurate, you certainly wouldn’t want to go plowing through the rings at any sort of speed. Fortunately, if you did find yourself within the rings, you wouldn’t need to worry too much. So long as you settled in with zero velocity compared to the bits around you, you’d very likely be quite safe; relative velocities in small regions would probably be very low. In other words, you’d be unlikely to get slammed by a  chunk moving at a greatly different speed.

And so long as rings are the topic:  in 2009 I posted a link to a YouTube video that was created to show what the skies of Earth would look like if Earth had a Saturn-like ring system. Neato! But I missed this last year… space artist Ron Miller created a number of paintings of an Earth with rings:

What if Earth Had Rings Like Saturn?

There are some spiffy paintings, but by far my favorite is this:

Here, along the Tropic of Capricorn at 23° south latitude, a 180-degree panorama gives an idea of what the rings might look like. The darkened area in the middle of the ring is Earth’s shadow, shown at its fullest extent around midnight. Sunlight passing through the atmosphere leaves the edge of the shadow tinged with an orange-pinkish color.
