TL;DR: The Hayabusa2 spacecraft measured the mass, size, shape, density, and spin rate of asteroid Ryugu, showing that it is a porous rubble pile, and observations of Ryugu's shape, mass, and geomorphology suggest that Ryugu was reshaped by centrifugally induced deformation during a period of rapid rotation.

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: The Hayabusa2 team's study of the near-Earth carbonaceous asteroid 162173 Ryugu, at which the spacecraft arrived in June 2018, describes Ryugu's geological features and surface colors and combined results from all three papers to constrain the asteroid's formation process.

TL;DR: The authors conclude that the asteroid experienced a prior period of strong solar heating caused by changes in its orbit, and suggest that Ryugu previously experienced an orbital excursion near the Sun.
