The elemental composition of the Earth comes from its fiery past, through accretion of various solar system objects. New samples collected by the Hayabusa2 space mission provide insight into the origins of moderately volatile elements such as zinc and copper. Tokyo Tech researchers have linked the material from the Cb-type asteroid, Ryugu, to the elemental composition of the Earth. Their results suggest that Ryugu-type material played a significant role in the genetic heritage of the Earth's elemental composition.
