Exact figures for the number of asteroids in the asteroid belt vary widely, but astronomers generally agree there are millions of objects of at least one kilometer in diameter. That sounds like a lot, but it turns out the asteroid belt is a fairly empty and lonely place.
The average distance between main belt asteroids is just shy of 1,000,000 kilometers (600,000 miles). For comparison, the distance between the Earth and Moon is a little less than 400,000 kilometers (240,000 miles).
But for hotshot space pilots like myself, there are still some opportunities to zigzag between and around dangerously close asteroids, perhaps while being pursued by hordes of Imperial TIE Fighters.
Over a hundred asteroids are known to have at least one tiny moon. Binary and trinary asteroids have also been discovered. Those are pairs or trios, respectively, of asteroids of roughly equal mass that are locked into orbit around their common center of gravity.
And of course when asteroids collide, they often form debris fields. This debris can linger for weeks before recombining as a rubble pile asteroid. Maybe these chaotic post-collision debris fields are just the perfect place to try evading the forces of the Evil Empire. Assuming you can find one.
