Composition and origin
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.
