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

Soh Kam Yung#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."

Tiny meteorites are everywhere. Here’s how to find them.
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.

Can you really find micrometeorites in your gutter? Well…
I collect meteorites, and have quite a few knocking around my home office. Some are big — fist-sized, with one I bring with me when I give talks about impacts so people can hold a piece of an asteroid in their hand — but most are pretty small, like the size of a finger from the last joint to the tip. A few are pebbles (generally well-known ones with special scientific interest, making bigger pieces hard to obtain), and a couple of are sand-grain-sized (one is from the Moon and the other from Mars).
