micrometeoroids
Tiny cosmic projectiles
Micrometeoroids are tiny particles of rock or metal traveling through space at high velocities, typically smaller than a grain of sand.
Though minuscule, their extreme speed makes them a hazard to spacecraft and satellites, capable of puncturing equipment or degrading surfaces over time.
Space agencies design protective shielding to guard against micrometeoroid impacts.
