TL;DR: Spectral observations and a principal components analysis suggest that Ryugu originates from the Eulalia or Polana asteroid family in the inner main belt, possibly via more than one generation of parent bodies.

TL;DR: In this article , the authors analyzed 17 samples of the carbonaceous asteroid Ryugu and found that carbon dioxide-bearing water inclusions are present within a pyrrhotite crystal, indicating that Ryugu's parent asteroid formed in the outer Solar System.

TL;DR: In this article, the authors used high-resolution thermal and optical imaging of Ryugu's surface to find high porosity boulders on the floor of fresh small craters ( 70%, which is as high as in cometary bodies) and suggested that these boulders are probably the most pristine parts of the planetesimals that formed Ryugu.
