About 40,000 metric tons of #extraterrestrial material rain down on planet Earth 🌍 every year. Sometimes those #meteorites ☄️ are relatively large: boulder-sized chunks of iron or small, blackened rocks. But most of the material arrives here in the form of #micrometeorites https://www.astronomy.com/science/thinking-small-uncovering-the-secrets-of-micrometeorites/

Roughly 1,600 tons of #micrometeorites and 3,600 tons of cosmic spherules reach the surface every year. Lower density and higher porosity suggest a #cometary ☄️ origin, and higher density and lower porosity suggest a #meteoritic origin https://www.sciencealert.com/5-200-tons-of-micrometeorites-are-raining-down-on-earth-s-surface-every-year

#JWST suffered a large than expected micrometeorite impact. It's still fine.

"Between May 23 and 25, NASA’s James Webb Space Telescope sustained an impact to one of its primary mirror segments.
[...]
This most recent impact was larger than was modeled, and beyond what the team could have tested on the ground."

Yes, there are micrometeorites in the debris that land on your roof. But it isn't much compared to what else is up there. Entertaining article by Phil Plait.
