Scientists estimate that an average meteoroid could lose around 90% of its mass during atmospheric flight. A meteoroid is a small, rocky or metallic object in outer space.2. The amount of meteorites is much smaller than that of gold, platinum, diamonds, and emeralds. Find meteorites, identify them, and connect them to magnets. [In this image] I used this magnetic swivel hook purchased from Amazon. Once theyre free of the magnet, any micrometeorites on the plastic will fall into the clean sandwich bag. Some meteors burn up in the atmosphere and never make it to the surface of the Earth, but some do. Another benefit of neodymium magnets is that they are relatively inexpensive, making them a great option for budget-conscious hunters. Iron meteorites can be very valuable, but are quite rare. Holding the magnet over the first, labeled sandwich bag, pull away the plastic layers. Meteorites are basically fragments of comets and asteroids that enter the earth atmosphere and survive to reach the ground.
