Micrometeoroid: A Small but Significant Threat

Micrometeoroids are tiny particles of dust and rock that orbit the Sun, just like planets and asteroids. However, what sets them apart is their extremely small size, usually ranging from a few micrometers to a few centimeters in diameter. Despite their small size, micrometeoroids pose a significant threat to spacecraft, satellites, and even the Earth's atmosphere.

In space, micrometeoroids move at high speeds, often exceeding 20 kilometers per second. When they collide with spacecraft or satellites, they can cause damage ranging from minor scratches to significant holes. Over time, these impacts can degrade the structural integrity of these objects, leading to malfunctions or even complete failure. Moreover, the high
