How big are the pieces in meteor showers or shooting stars?

The particles that enter our atmosphere during a meteor shower or when you see a shooting star are usually very small. Some are no larger than a grain of sand. Thousands of these particles enter our atmosphere each day and most of them burn up well before they can reach the ground.
