Collision (and effects)

Large debris >10 cm1–5 × 104 (Low)
(17,800 in 2001)
1/1000
(Satellites, rocket bodies, fragmentation material).(collision results in total breakup and loss of capability)

Medium 1 mm–10 cm1–5 × 106 (Medium)
(0.5 × 106 in 2001)
1/100
Fragmentation debris, explosion debris, leaking coolant.(collision could cause significant damage and possible failure)

Small <1 mm>1012 (High)
(3 × 108 in 2001)
Almost 1/1
Aluminum oxide particles, paint chips, exhaust products, bolts, caps, meteoric dust.collision should cause insignificant damage
