  • A new analysis of Dawn’s observations reveals Vesta’s moment of inertia, indicating limited central density variation. This finding suggests that Vesta did not undergo full differentiation, challenging conventional models of Vesta’s formation and evolution.

  • An analysis of the orbital motion of Saturn’s moon Mimas shows that a recently formed global subsurface ocean lies beneath its cratered icy shell and that this ocean is probably still evolving.

  • SPHERE at the VLT observed Hygiea, the fourth largest body in the main belt and the parent body of a big asteroid family, at unprecedented spatial resolution. Its unexpected spherical shape without any impact crater is explained by numerical simulations with a big impact that fluidized the body, reassembling it in a rotational equilibrium regime.

  • Gravity and shape measurements for Ceres obtained from the Dawn spacecraft mission show that it is in hydrostatic equilibrium with its inferred normalized mean moment of inertia of 0.37, suggesting that Ceres has a rocky chondritic core overlaid by a volatile-rich icy shell.
