What characterizes the objects between 1 cm and 10 cm regarding tracking and collision risk?

Answer

Objects too small to be reliably tracked but large enough to cause substantial damage

The size range spanning from one centimeter to ten centimeters represents a critical gap in tracking capabilities, yet these objects pose a severe threat profile. Current tracking systems cannot reliably monitor the vast number of items in this range. However, their size is still sufficient that impact would lead to substantial system damage, distinguishing them from the microscopic particles. Because of their high number and tracking limitations, they are considered an unavoidable statistical risk that mission planners must account for, even if individual trajectories cannot be predicted with certainty.
