How to Tell if a Rock Is a Meteorite? | Sciencing

You could easily find nonextraterrestrial, metal-containing rocks or iron slugs on Earth, however. Meteorites have a unique quality because the iron also contains about 7 percent nickel. Meteorites also have a higher density than Earth rocks. You can compare two rocks of similar size. One should be the rock you suspect is a meteorite.
