by Saturn and Methone's gravity, its density can be estimated: , among the lowest density values obtained or inferred for a Solar System body.

Methone's low-density regolith may respond to impacts in a way that smooths its surface more rapidly than on rigid moonlets such as Janus or Epimetheus. Movement of the regolith may also be facilitated by more "exotic" processes such as electrostatic effects.

Methone has two sharply defined albedo regions, with albedos of 0.61±0.06 and 0.7±0.03. The darker
