Question

Name the Galilean moons.

Answer 1

As, Jupiter shares its name with the king of the gods.In addition to being the largest planet in our Solar System – with two and a half times the mass of all the other planets combined – it is also home to some of the largest moons of any Solar planet. Jupiter’s largest moons are known as the Galileans, all of which were discovered by Galileo Galilei and named in his honor.

They include : lo, Europa, Ganymede, and Callisto

​​​​​(and also are the Solar System’s fourth, sixth, first and third largest satellites, respectively.)

1. Io :- The innermost is Io, which is named after a priestess of Hera who became Zeus’ lover. With a diameter of 3,642 kilometers, it is the fourth-largest moon in the Solar System.

2. Europa:

   The second innermost Galilean moon is Europa, which takes its name from the mythical Phoenician noblewoman .At 3121.6 kilometers in diameter, it is the smallest of the Galileans, and slightly smaller than the Moon.

3. Ganymede:

   Next up is Ganymede. At 5262.4 kilometers in diameter, Ganymede is the largest moon in the Solar System. While it is larger than the planet Mercury, the fact that it is an icy world means that it has only half of Mercury’s mass. It is also the only satellite in the Solar System known to possess a magnetosphere, likely created through convection within the liquid iron core.

4. Callisto:

   Callisto is the fourth and farthest Galilean moon. At 4820.6 kilometers in diameter, it is also the second largest of the Galileans and third largest moon in the Solar System.
