Can humans survive on Callisto?
As a result, humans could live on the surface of Callisto with just a sufficiently strong radiation attenuating glass between them and the remaining radiation from its host planet. In addition to this relative safety from radiation, this moon is composed of around 40% water.
Is there ice on Callisto?
Callisto has an icy surface covered by craters of various shapes and sizes, including bowl-shaped craters and craters with multiple rings. Data gathered by the Galileo spacecraft indicate Callisto may have a subsurface ocean and scientists estimate it may be 155 miles (250 kilometers) below the surface.
Is Jupiter’s moon Callisto habitable?
Callisto has a very thin atmosphere, is thought to contain an ocean, and is therefore another possible contender for life beyond Earth. However, its distance from Jupiter means it doesn’t experience such a strong gravitational pull, so it’s not as geologically active as the other Galilean moons of Io and Europa.
Does Callisto moon have water?
Investigation by the Galileo spacecraft revealed that Callisto may have a small silicate core and possibly a subsurface ocean of liquid water at depths greater than 100 km. The surface of Callisto is the oldest and most heavily cratered in the Solar System. Its surface is completely covered with impact craters.
What is Jupiter’s coldest moon?
It is the smallest of the Galilean moons. Temperature: Europa’s surface temperature at the equator never rises above minus 260 degrees Fahrenheit (minus 160 degrees Celsius). At the poles of the moon, the temperature never rises above minus 370 F (minus 220 C).
Can Titans be habitable?
Potential for Life The discovery of a global ocean of liquid water adds Titan to the handful of worlds in our solar system that could potentially contain habitable environments.
What if Earth’s gravity doubled?
If gravity were twice as strong , bodies possessing the same construction and mass as our flora and fauna would weigh twice as much and would collapse. It’d be “timber!” for tall, thick trees such as redwoods.
What is the surface temperature of Callisto?
It is the third largest moon in the solar system, after Ganymede and Titan. (Earth’s moon is fifth largest, following Io.) Temperature: The mean surface temperature of Callisto is minus 218.47 degrees Fahrenheit (minus 139.2 Celsius).
How big is Callisto moon?
Callisto Moon Facts. Callisto is the second largest moon in the Jupiter system and is nearly the size of Mercury. It is the most distant of the Galilean moons from Jupiter. It was discovered in 1610 by Galileo Galilei and independently observed by Simon Marius. Callisto size compared to the Moon and Earth.
How is Callisto different from the other Galilean moons?
It also experiences fewer tidal influences than the other Galilean moons because it orbits beyond Jupiter’s main radiation belt. Callisto is tidally locked, so the same side always faces Jupiter. Size: At 3,000 miles (4,800 km) in diameter, Callisto is roughly the same size as Mercury.
How far away is Callisto from the Sun?
Callisto’s circumference at its equator is about 9,410 miles (15,144 kilometers). Callisto orbits about 1,170,000 miles (1,883,000 kilometers) from Jupiter and Jupiter orbits about 484 million miles (778 million kilometers) from our Sun.
