IIE iron meteorite

IIE
— Group —
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.

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.

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