The Weekeroo Station meteorite, an IIE iron meteorite

Type| Iron
Structural classification| Octahedrite
Class| Nonmagmatic
Parent body| Probably 6 Hebe
Total known specimens| 21 as of 2009[update]

The iron meteorites of the IIE chemical type are octahedrites of various coarseness, most of which contain numerous inclusions of recrystallized stony silicates.

## Composition and origin[edit]

They have mineral compositions and oxygen isotope ratios very similar to the H chondrites, which makes it probable that they originate from the same parent body. The best candidate for this parent body is the S-type asteroid 6 Hebe.[1] Unlike most iron meteorites, the type IIE are thought to have been melted out of the chondritic surface of the parent asteroid by impacts during its early history.

## Rarity[edit]

It is a rare type with 24 known members as of 2020.[2]
