Callisto is composed of rock and ice and is the least dense of the Galilean moons.
The Galilean moons orbit the planet Jupiter.
Jupiter
Jupiter. The "Galilean" moons are the four largest moons, which are so large that Galileo was able to see them orbiting Jupiter even with his relatively modest telescope.
Jupiter has 79 moons and there are 4 major moons; The Galilean moons named after Galileo.
To answer the question very literally: Yes. The Galilean satellites follow the same pattern of density versus increasing distance from Jupiter that the planets' density follows versus distance from the sun. The specific pattern is: No pattern at all. Earth ... 3rd from the sun ... is the most dense planet, while Saturn ... 6th planet from the sun ... is the least dense. So there is no "just as" to compare to.
The Galilean moons orbit the planet Jupiter.
No. It is a moon of Mars. The Galilean moons are moons of Jupiter.
The Galilean moons orbit Jupiter.
Because they were discovered first by Galileo.
The Galilean moons were discovered by Galileo Galilei in 1610.
No. There are four Galilean moons: Io, Europa, Ganymede, and Callisto.
They were discovered by Galileo.
The Galilean moons are the four largest moons of Jupiter, so called because they were discovered by Galileo Galilei.
The Galilean moons of Jupiter are (from most massive to least massive) Io, Europa, Ganymede, and Callisto.
From what I have read, the closer one of the Galilean Moons is to Jupiter, the hotter is their interior (as a result of tidal heating due to Jupiter's gravity). The outer ones have more of an ice core. The inner ones less. When it melts, the water makes it way to the surface being less dense than the surrounding rock, and evaporates off, leaving the heavier rock forming most of the crust. Therefore the more dense the inner Galilean Moons.
Galilean
The Galilean moons are Io, Europa, Ganymede, and Callisto, all of which orbit Jupiter. The term "Galilean" does not denote anything special about the moons other than that they were discovered by the astronomer Galileo Galilei.
