Which Galilean moon is characterized as being the densest, composed almost entirely of rock and metal with negligible water ice?
Answer
Io
Io is the innermost moon and is extremely dense, consisting primarily of silicate rock and metal, having formed in an environment too hot for water ice to survive.
