Lunar and Martian meteorites, and most achondrites (stone meteorites without chondrules) contain little or no iron and even a powerful magnet will generally have no effect on them. However, these meteorite types are so extremely rare that, as a general rule, we discount specimens that will not adhere to a magnet. 1) Most meteorites are attracted to strong magnets, though many common Earth rocks are also attracted to magnets. 2) Most meteorites are denser than the average Earth rock. In other words meteorites are typically heavier than Earth rocks of the same size. 3) Stony meteorites (Chondrites and Achondrites) often have an obvious fusion crust. below) is covered by a fusion coating.

An extremely small percentage of meteorites do not show strong attraction to a magnet. Those meteorites look similar to volcanic rocks from Earth, and are not metallic in appearance. Rare Earth Magnet Photo 2. Most meteorites will adhere strongly to a good magnet. Are meteorites heavy? Most meteorites are much denser than ordinary Earth …Non-terrestrial Chromite is usually (but not always) associated with iron-nickel meteorites. So the fact that it is not attracted by a magnet makes it unlikely to be a meteorite and certainly unlikely to be a chromite meteorite. See below for more information on helping to ID a possible meteorite.When meteorites enter the atmosphere, they’re moving really quickly. Usually ~ 20 to 40 kilometers per second. For comparison, the Space Shuttle used to enter the upper atmosphere at ~8 kilometers per second. This causes intense heat and pressure to act on the surface of the rock. The outside of the meteorite vaporizes, and a thin molten ...The pictures on this page are of authenticated, well-studied meteorites, presented here to show their visual diversity and are for reference only.

More than 95% of all meteorites contain iron-nickel (FeNi) metal. As a consequence, meteorites have concentrations of nickel that are much greater than that of nearly any terrestrial rock. “Iron-nickel” means that the metal is mostly iron but it also contains 5-30% nickel.
