IRON
meteorites are composed mainly of iron (Fe) and nickel (Ni) in the form of two nickel-iron alloys, kamacite and taenite. Iron meteorites are easy to tell apart from ordinary Earth rocks because of their metallic appearance and high density. Iron meteorites tend to be bigger than stony meteorites or stony-iron meteorites, because they usually survive passage through the atmosphere intact and suffer much less from the effects of ablation. All known iron meteorites have a combined mass of more than 500 tons – about 86% of the mass of all known meteorites. Iron meteorites are rare and only account for about one in 20 of observed falls.
