Kirkwood gap
What would it be like to flying through an asteroid belt?
Lots of dodging and avoiding collision like in Star Wars.
Very few asteroids, possibly wouldn't see one at all.
There would be a few asteroids to avoid, but not as many as they show in the movies, probably you would only see about ten at a time.
Thousands of tiny particles, closer to the size of pebbles and boulders, but no large, house sized rocks.

Smaller than our moon
Slightly larger than Earth
Close to the size of Jupiter
About the size of a blue whale
