Micrometeorites Micrometeorites Meteors are small bits of rock and other matter within the solar system. Occasionally these meteors enter our atmosphere. Most are small and burn up completely in the atmosphere. Occasionally they do pass through, or at least bits of them, and strike the earth's surface. These are meteorites, and can either be rocky or metallic.
Some meteors are so tiny that they fall through the atmosphere without burning up.
They are so small in fact that they float around in the atmosphere, eventually reaching the ground with rain droplets or heavier dust particles. The best times to collect micrometeorites are after meteor showers. The dish needs to be very clean. Let it sit outdoors long enough to fill. If you don't live where it rains very much, fill the pan with distilled water and let it sit outside for a few days.
