Flying objects out in space have no weight only the gravity of the body they hit imparts weightiness to the projectile, so an impact would not be as shattering hitting a small chunk of stuff like this as it would if it hit the earth for instance.

"...Flying objects out in space have no weight only the gravity of the body ..."

you're close. they have mass, not gravity. but the mass and velocity would still cause quite collision.
