What differentiates 'space debris' from 'meteoroids' in official categorization?
Answer
Meteoroids are natural particles of dust or rock, while debris is artificial
The official designation of 'space debris' is strictly reserved for artificial remnants created by human activities in orbit. Meteoroids, conversely, are natural cosmic hazards, consisting of particles of dust or rock that enter the Earth's atmosphere. Although both types of objects present a similar kinetic threat to working spacecraft due to their high relative velocities, the source—human-made versus natural—is the key factor in their categorization. From an engineering perspective, both are dangerous, but only the artificial junk falls under the specific monitoring protocols associated with space debris.
