Notice that both accretionary and collisional orogens developed in converging plate margins. This configuration is contradicted by widespread Precambrian collisional events between Australia and Africa. These kinds of planet-disk interactions can be modeled numerically using collisional grooming techniques. This includes an extra term in Ohm's Law which models the collisional resistivity. The relaxation time identifies collisionless vs. collisional stellar systems. These may represent collisional debris generated from impacts with this satellite. The event was brief but gentle, saving Triton from collisional disruption. This type of geometry is typically found in the hinterland of a collisional zone. This difference may be due to a past collisional disruption of Proteus. Such a collisional domino effect of satellite destruction is known as the Kessler syndrome. The difference is considerably lower than that of most suspected collisional satellites. They often occur as collisional families or groups. Hence they may have arisen from the same collisional event. Collisional shattering slowly depletes the Jupiter trojan population as fragments are ejected.
