· Calculate the rock's density if it feels heavier than normal. Meteorites are solid pieces of rock that are usually densely packed with metal. If the rock you've found looks like a meteorite, compare it to other rocks to ensure it's relatively heavy, then calculate its density to determine if it's a meteorite.

How to Identify a Meteorite. (The Magnet Test and Native Iron) About 90% of meteorites will attract a magnet. This is true for iron meteorites and for stone meteorites. You don't need a special magneta refrigerator magnet like will do. Here is how to check. In meteorites almost all of the attraction is the result of native iron.

3. Magnetic Properties Magnetic Properties A lot of meteorites contain shiny ironnickel metal grains or consist largely of ironnickel metal. The iron in the metal attracts a magnet. Is a magnet attracted to the surface of your sample? If so, you might have a meteorite. But remember that a lot of normal rocks on the Earth are also magnetic.

Magnetite is sometimes called lodestone. It is strongly magnetic. It was used by the ancient Chinese to make the first magnetic compasses. The chemical formula is Fe 3 O 4.: Hematite is one of the most prevalent and useful forms of iron on our planet. It is a common iron ore and is often used in jewelry and other decorative items.

If the magnet pulls towards the stone then you are on the right track. However there are still a lot of Earth rocks that will also attract a magnet, so this test is by no means conclusive. A very few meteorites will not attract a magnet, so read on and see if any of the other features are present.

Marcasite and troilite are usually nonmagnetic, arsenopyrite and pyrrhotite are very weakly magnetic, and other minor forms have varying strengths based on chemical make up. Leaving the sample near a strong magnetic field will usually give the metal magnetic properties after a while though.

Density: Meteorites are usually quite heavy for their size, since they contain metallic iron and dense minerals. Magnetic: Since most meteorites contain metallic iron, a magnet will often stick to them. For "stony" meteorites, a magnet might not stick, but if you hang the magnet by a string, it will be attracted.
