Asteroid adrift

The Muonionalusta meteorite is the oldest meteorite known so far and hit one million years ago in northern Scandinavia. The meteorite has since survived ice ages 4 and has moved several times during this period. The meteorite is almost certainly an asteroid beaten adrift.

Unique meteorite structure

The meteorite is known for its beautiful Widmanstättenstructuren (octahedriet). This is the triangular structure which becomes visible in the etching of the meteorite. These crystal forms caused by the meteorite it took millions of years to cool. The structures are therefore unique to meteorites and do not come on earth as iron cools much faster.
