What are 3 interesting facts about Ganymede?
Facts about Ganymede
- Age: Ganymede is about 4.5 billion years old, about the same age as Jupiter.
- Distance from Jupiter: Ganymede is the seventh moon and third Galilean satellite outward from Jupiter, orbiting at about 665,000 miles (1.070 million kilometers).
- Size: Ganymede’s mean radius is 1,635 miles (2,631.2 km).
How does Ganymede compare to Earth?
With a mean radius of 2634.1 ± 0.3 kilometers (the equivalent of 0.413 Earths), Ganymede is the largest moon in the solar system and is even larger than the planet Mercury. However, with a mass of 1.4819 x 1023 kg (the equivalent of 0.025 Earths), it is only half as massive.
What is special about Ganymede?
Ganymede is the only moon known to have its own magnetic field – a discovery made by NASA’s Galileo spacecraft in 1996. The magnetic field causes auroras, which are ribbons of glowing, hot, electrified gas, in regions circling the north and south poles of the moon.
Is Ganymede bigger than Earth?
Size. With a diameter of about 5270 km and an mass of 1.48×1020 tonnes, Ganymede is the largest and most massive moon in the Solar System. It is slightly more massive than the second most massive moon, Saturn’s satellite Titan, and is more than twice as massive as the Earth’s Moon.
Can you see Ganymede from Earth?
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 difference between Ganymede and Earth’s moon?
page L5 – Comparison: Moon v Ganymede. While the mass of the Earth is 81.22 times that of the Moon. The first ratio is 158 times larger than the second. The radius of Jupiter is 27.14 times that of Ganymede, while the radius of the Earth is only 3.67 times that of the Moon.
Can we land on Ganymede?
So far spacecraft have landed on Venus, the Moon, Mars and Saturn’s moon Titan; landing on Ganymede would mark the sixth body in the Solar System (including Earth) that humanity has left its mark upon. The Ganymede Lander is still in a concept stage at the moment.

What if Ganymede was Earth’s moon?
And so would billions more around the world. Ganymede’s gravitational pull could even be strong enough that the Earth would become tidally locked to it. This would mean that one side of the planet would always be facing this moon. This would be good news if you were on that side of the planet.
Can we live on Ganymede?
Ganymede is the only moon with a magnetosphere, albeit overshadowed by Jupiter’s magnetic field. Because of this magnetic field, Ganymede is one of only two Jovian moons where surface settlements would be feasible receives about 0.08 Sv of radiation per day.
Who kidnapped Ganymede planet?
According to a myth, Zeus turned into an eagle and abducted Ganymede, bringing him to Mount Olympus.
What planet has 4 moons around it?
planet Jupiter’s
The planet Jupiter’s four largest moons are called the Galilean satellites after Italian astronomer Galileo Galilei, who first observed them in 1610.
How does Earth’s Moon compare to Ganymede?
Size comparison of Earth, the Moon, and Ganymede. The radius of Earth at the equator is 6,378 kilometers (3,963 miles). Ganymede has a mean radius of 2634.1±0.3 km (about 1636 miles, 0.413 Earths). Moon’s radius is 1,737.1 km (1079 mi).
What would happen if Ganymede was our Moon?
What’s more, Ganymede’s crust is very rich in water ice. If it was orbiting Earth that ice would quickly melt and turn it into an ocean moon. It would also quickly develop an atmosphere, possibly mostly water vapor but probably also with a bunch of other volatiles that was trapped in the ice.
Is it true that Ganymede orbits Jupiter?
Ganymede orbits Jupiter at a distance of about 665,000 miles (1,070,400 kilometers). It is third among the Galilean satellites and the orbit period is every seven days and three hours. Several spacecraft orbiting or completed flybys of Jupiter have explored Ganymede. The first mission to explore Ganymede up close was the Pioneer 10.
Is Jupiter’s moon Ganymede a gas or solid planet?
Of course, many people think that the gas planets are solid and are surprised when they turn out not to be. Ganymede is solid on the surface, but beneath this is a large ocean of water. Deeper than this is likely frozen ice and rocks, with a iron core middle just like Earth.
