How Fast Is Asteroid Belt (average)?

Asteroids in the main belt orbit the Sun at 20,000 m/s on average — but they are typically 1,000 km apart. Contrary to science fiction depictions, navigating the belt is essentially empty space; collisions between asteroids are rare events.

Star Wars notwithstanding, the asteroid belt is mostly empty — asteroids are typically 1,000 km apart on average.
