The Romans called it "the star of Jupiter", as they believed it to be sacred to the principal god of Roman mythology, whose name comes from the  compound Dyēu-pəter, meaning "Father Sky-God", or "Father Day-God". In turn, Jupiter was the counterpart to the mythical Greek Zeus, also referred to as Dias, the planetary name of which is retained in modern Greek. The ancient Greeks knew the planet as Phaethon, meaning "shining one" or "blazing star." As supreme god of the Roman pantheon, Jupiter was the god of thunder, lightning and storms, and appropriately called the god of light and sky.

The moons of Jupiter

Io

is the innermost and third-largest of the four Galilean moons of the planet Jupiter. With over 400 active volcanoes, Io is the most geologically active object in the Solar System. Io's volcanism is responsible for many of its unique features. Its volcanic plumes and lava flows produce large surface changes and paint the surface in various subtle shades of yellow, red, white, black, and green.

Europe

is the smallest and second innermost of the four Galilean moons orbiting Jupiter. Slightly smaller than Earth's Moon, Europa is primarily made of silicate rock and has a water-ice crust and probably an iron–nickel core. It has a very thin atmosphere, composed primarily of oxygen and its surface is striated by cracks and streaks.

Ganymede

is the biggest and third innermost of the four Galilean moons orbiting Jupiter. Ganymede is the largest and most massive of the Solar System's moons. It is 8% larger than the planet Mercury. Ganymede orbits Jupiter in roughly seven days and is in a 1:2:4 orbital resonance with the moons Europa and Io, respectively.

Callisto

is the second-largest and outermost moon of the four Galilean moons orbiting Jupiter. Callisto is composed of approximately equal amounts of rock and ices. Investigation by the Galileo spacecraft revealed that Callisto may have a small silicate core and possibly a subsurface ocean of liquid water at depths greater than 100 km. The surface of Callisto is the oldest and most heavily cratered in the Solar System.
