Interior Model of the possible interior composition of Io with an inner iron or iron sulfide core (in gray), an outer silicate crust (in brown), and a partially molten silicate mantle in between (in orange) Composed primarily of silicate rock and iron , Io is closer in bulk composition to the terrestrial planets than to other satellites in the outer solar system, which are mostly composed of a mix of water ice and silicates. Io has a density of 3.5275 g/cm 3 , the highest of any moon in the Solar System ; significantly higher than the other Galilean satellites and higher than the Earth's moon. [59] Models based on the Voyager and Galileo measurements of the moon's mass, radius and quadrupole gravitational coefficients (numerical values related to how mass is distributed within an object) suggest that its interior is differentiated between an outer, silicate-rich crust and mantle and an inner, iron- or iron sulfide -rich core . [39] The metallic core makes up approximately 20% of Io's mass.
