Achondrites are rare, however. Only 2.5% of the ~1500 stony meteorites that have been found in the U.S. are achondrites.About one hundred different lunar meteorites (lunaites) and approximately thirty Martian meteorites (SNCs) have been discovered on earth, and they all belong to the achondrite …

Meteorites are classified into three main types: stones, stony-irons, and irons. Stones are similar to rocks found on the earth in that they are composed primarily of silicate minerals, that is, compounds consisting of silicon, oxygen, and various metallic elements. Irons are made primarily of iron and nickel in varying proportions.In 1996, a team of scientists led by David McKay of NASA’s Johnson Space Flight Center announced that they had discovered evidence for microscopic fossil life in a meteorite from Mars.

Dotted lines denote ROI 1 and 2.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.

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 ... Iron Meteorites Iron 01. Some may disagree, but iron meteorites do not have fusion “crusts” so much as “patinas.” Patinas do not chip off, as on the stony meteorites above. Regmaglypts are common. I think the shiny spots are abrasions exposing the underlying shiny metal. Iron 02. Rounded, no sharp edges. Covered with regmaglypts. Iron 03.
