What is the diameter of Ganymede?

3,273.5 miGanymede / Diameter

Ganymede has a diameter of about 5,270 km (3,275 miles), which makes it larger than the planet Mercury. It orbits Jupiter at a distance of 1,070,000 km (665,000 miles).

Can a human 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.

Can humans live Ganymede?

However, it is too thin to support life as we know it; it is unlikely that any living organisms inhabit Ganymede. Magnetosphere: Ganymede is the only satellite in the solar system to have a magnetosphere.

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.

Are there any moons bigger than Earth?

Titan is the second largest moon in our solar system. Only Jupiter’s moon Ganymede is larger, by just 2 percent. Titan is bigger than Earth’s moon, and larger than even the planet Mercury.

How big is Ganymede compared to the Sun?

The ninth-largest object (including the Sun) of the Solar System, it is the largest without a substantial atmosphere. It has a diameter of 5,268 km (3,273 mi), making it 26 percent larger than the planet Mercury by volume, although it is only 45 percent as massive….Ganymede (moon)

Discovery
Composition by volume mostly oxygen

Can Ganymede be terraformed?

It’s possible that Ganymede has liquid water under the surface. If this is correct, it could be terraformed and heated by adding greenhouse gases such as Sulfur Hexafluoride and Nitrogen Trifluoride.

How long is a day on Ganymede?

seven Earth days
LONG DAYS. Ganymede’s day is just over seven Earth days long, the same amount of time it takes Ganymede to orbit Jupiter once.

Is Titan moon habitable?

Additionally, Titan’s rivers, lakes and seas of liquid methane and ethane might serve as a habitable environment on the moon’s surface, though any life there would likely be very different from Earth’s life.

How big is Titan vs Earth?

The radius of Titan is about 1,600 miles making it smaller than half the size of Earth (3,963 miles) but larger than the Earth’s moon (1,079.6 miles).

Why is Titan Not a planet?

Because Titan is less massive than Earth, its gravity doesn’t hold onto its gaseous envelope as tightly, so the atmosphere extends to an altitude 10 times higher than Earth’s—nearly 370 miles (600 kilometers) into space.

Can we terraform Titan?

To break it down, only Enceladus and Titan appear to be viable candidates for terraforming. However, in both cases, the process of turning them into habitable worlds where human beings could exist without the need for pressurized structures or protective suits would be a long and costly one.

Is the mass on Ganymede smaller than on Earth?

Mass (weight, force of gravity on earth and force of gravity on object would change as you moved) Ganymede, has a mass of 1.48 x 1023 kg. Mars is smaller than

How big is Ganymede relative to Earth?

The largest moon and also the largest non-planet in the Solar System, Ganymede has a mean radius of 2634.1±0.3 km (about 1636 miles, 0.413 Earths). For comparison, our Moon’s radius is 1,737.1 km (1079 mi). What if Ganymede was the Earth’s second moon? That’s how it would look in the sky if it was at the same distance as the Moon.

Is Ganymede the largest planet in the Solar System?

The largest of Jupiter’s moons, Io, Europa, Ganymede and Callisto, are known as Galilean moons, after being discovered by Italian astronomer Galileo Galilei in January 1610. Ganymede is not only Jupiter’s largest moon, but the largest moon in our solar system, and the only moon with its own magnetic field.

Which Moon is bigger Titan or Ganymede?

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.
