> How did the Voyagers avoid hitting asteroids when exiting the solar system? I thought there was a huge cloud of asteroids surrounding our solar system.

The same way the Saturn probes went right through the rings and didn't hit anything.

Even if it looks like a "cloud" or "ring", that doesn't mean that it is "dense". There are whopping distances between objects in space.

It is way, way, way more difficult to actually "hit" something in space than it is to avoid something.
