What are the 4 satellites of Jupiter?
The Galilean Moons These large moons, named Io, Europa, Ganymede, and Callisto, are each distinctive worlds.
What are the 4 major Galilean satellites of Jupiter?
Galilean moons. In January 1610, Italian astronomer Galileo Galilei discovered four of Jupiter’s moons — now called Io, Europa, Ganymede and Callisto. He originally referred to the individual moons numerically as I, II, III, and IV.

What are the main satellites of Jupiter?
Jupiter has four large satellites, known as the Galilean satellites: Io, Europa, Ganymede, and Callisto.
What is distinctive about Jupiter’s satellite Io?
What is distinctive about Jupiter’s satellite Io? Io has active sulfurous volcanic centers. Other than Earth & Neptune’s moon Triton, Io is the only volcanically active body discovered in our solar system.
Which of the four satellites appears closest to Jupiter which of the four satellites appears closest to Jupiter Callisto Europa Io Ganymede?
The Galilean satellites were first seen by the Italian astronomer Galileo Galilei in 1610. Shown from left to right in order of increasing distance from Jupiter, Io is closest, followed by Europa, Ganymede, and Callisto.
What does Jupiter look like from Io?
From the surface of Io, Jupiter would subtend an arc of 19.5°, making Jupiter appear 39 times the apparent diameter of Earth’s Moon.
What is the largest satellite of Jupiter?
Ganymede. Ganymede is the largest satellite in our solar system. It is larger than Mercury and Pluto, and three-quarters the size of Mars.
Did the Earth have 2 moons?
The simple answer is that Earth has only one moon, which we call “the moon”. It is the largest and brightest object in the night sky, and the only solar system body besides Earth that humans have visited in our space exploration efforts. The more complex answer is that the number of moons has varied over time.
What are the inner satellites of Jupiter called?
Inner satellites or Amalthea group: Metis, Adrastea, Amalthea, and Thebe. These orbit very close to Jupiter; the innermost two orbit in less than a Jovian day. The latter two are respectively the fifth and seventh largest moons in the Jovian system.
What are the satellites of Jupiter made of?
Jupiter’s regular satellites are believed to have formed from a circumplanetary disk, a ring of accreting gas and solid debris analogous to a protoplanetary disk. They may be the remnants of a score of Galilean-mass satellites that formed early in Jupiter’s history.
How did Jupiter’s satellites get their names?
The outer eight were named for lovers of Jupiter: Leda, Himalia, Lysithea, Elara, Ananke, Carme, Pasiphae, and Sinope. For the nonGalilean satellites, the “e” ending is reserved for satellites with retrograde orbits; those with normal orbits have names that end in “a.”.
What is the final Galilean moon satellite of Jupiter?
Callisto — the final Galilean Moon satellite of Jupiter is Callisto. It’s orbit is well beyond Jupiter’s main radiation belt and so the planets surface is much cooler then the other four satellites. However, it has the heaviest impacted surface in the solar system and shows no signs of geological activity since the impacts created its surface.
