A recent study published in Nature Astronomy identified the parent elements of asteroid Ryugu, a carbonaceous near-Earth object that is currently being explored by the Hayabusa2 mission. The study found that Ryugu is composed of components from two different sources: a rare type of meteorite from the inner solar system, and a rare type of interplanetary dust particle. The combination of these two elements suggests that Ryugu formed in the asteroid belt more than 4 billion years ago, and has been preserved in its current composition since then. This is an exciting discovery, as it provides valuable insight into the early history of our Solar System.
