What are the 4 moons of Jupiter?

In January 1610, Italian astronomer Galileo Galilei discovered four of Jupiter’s moons — now called Io, Europa, Ganymede and Callisto.

What are the names of the four Galilean moons?

A comparison “portrait” of Jupiter’s four Galilean moons Io, Europa, Gany- mede, and Callisto, each with different characteristics.

What are Jupiter’s 4 largest moons called?

The Galilean Moons The planet Jupiter’s four largest moons are called the Galilean satellites after Italian astronomer Galileo Galilei, who first observed them in 1610.

Why does Jupiter have 79 moons?

The further you travel from the sun, the weaker its gravitational pull on you becomes. Therefore, if Namouni is correct, the real Jupiter has 79 moons and counting because it’s an insanely massive planet that’s far enough away from the sun to avoid lunar theft.

Can I see Jupiter moons with binoculars?

Bottom line: You can see Jupiter’s four largest moons – Io, Europa, Ganymede and Callisto, known as the Galilean satellites – with your own eyes with the help of binoculars or a small telescope.

What is the fourth largest moon?

Io (Jupiter I) is the innermost of the four Galilean moons of Jupiter; with a diameter of 3642 kilometers, it is the fourth-largest moon in the Solar System, and is only marginally larger than Earth’s moon. It was named after Io, a priestess of Hera who became one of the lovers of Zeus.

What are the 2 biggest moons of Jupiter?

ESA Science & Technology – Jupiter’s largest moons From top to bottom, the moons are Io, Europa, Ganymede and Callisto. Europa is almost the same size as Earth’s moon, while Ganymede, the largest moon in the Solar System, is larger than planet Mercury.

How are Io, Europa and Callisto similar to Ganymede?

In the cases of Io, Europa and Callisto, these are identical to the Latin, but the Latin form of Ganymede is Ganymedes. In English, the final ‘e’ is silent, perhaps under the influence of French, unlike later names taken from Latin and Greek.

What kind of resonance does Ganymede have with Jupiter?

Outward from Jupiter, it is the seventh satellite and the third of the Galilean moons, the first group of objects discovered orbiting another planet. Ganymede orbits Jupiter in roughly seven days and is in a 1:2:4 orbital resonance with the moons Europa and Io, respectively.

How are the orbits of Europa and Ganymede related?

Ganymede participates in orbital resonances with Europa and Io: for every orbit of Ganymede, Europa orbits twice and Io orbits four times. Conjunctions (alignment on the same side of Jupiter) between Io and Europa occur when Io is at periapsis and Europa at apoapsis. Conjunctions between Europa and Ganymede occur when Europa is at periapsis.

Which is the only Galilean moon named after a male?

Ganymede is the only Galilean moon of Jupiter named after a male figure—like Io, Europa, and Callisto, he was a lover of Zeus. The Galilean satellites retain the Italian spellings of their names. In the cases of Io, Europa and Callisto, these are identical to the Latin, but the Latin form of Ganymede is Ganymedes.
