Is Callisto a moon?
Callisto is Jupiter’s second largest moon after Ganymede and it’s the third largest moon in our solar system. It’s almost as big as Mercury. Callisto’s circumference at its equator is about 9,410 miles (15,144 kilometers).
What material is Callisto made of?
Callisto is composed of approximately equal amounts of rock and ices, with a density of about 1.83 g/cm3, the lowest density and surface gravity of Jupiter’s major moons. Compounds detected spectroscopically on the surface include water ice, carbon dioxide, silicates, and organic compounds.
Does Callisto moon have water?
One of Jupiter’s largest moons, Callisto, may hold watery secrets beneath its surface, suggests a new analysis. The satellite’s icy crust may be the planetary equivalent of a blanket, insulating an underground ocean. Radioactivity at Callisto’s core provides ample heat to keep water from freezing.
Can you land on Callisto?
Callisto is the second largest and most distant of Jupiter’s Galilean moons. It is colorful and spotty in appearance. Callisto is included in the Planets Expansion DLC. Like Ganymede and Io, Callisto’s high gravity makes landing and return from the surface difficult with low thrust engines.
Could Callisto have life?
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.
What is the average temperature on Callisto?
This means that it also experiences less tidal influences than the rest of Jupiter’s moons, and it also doesn’t experience the horrors of the planet’s main radiation belt (which could irradiate, and thus kill, most life). But the average surface temperature of Callisto is -138 Celsius (-218.47 Fahrenheit),…
Is Callisto a Galilean moon?
Callisto is the fourth and farthest Galilean moon. At 4820.6 kilometers in diameter, it is also the second largest of the Galileans and third largest moon in the Solar System. Callisto is named after the daughter of the Arkadian King, Lykaon, and a hunting companion of the goddess Artemis .
What is Callisto’s rotational period?
Like most other regular planetary moons, Callisto’s rotation is locked to be synchronous with its orbit. The length of Callisto’s day, simultaneously its orbital period, is about 16.7 Earth days. Sep 15 2019
What is the moon Callisto made of?
The exact composition of the moon Callisto isn’t known but it is hypothesised to be made out of silicon and iron oxides and carbonates as well as chondrites and water ice.
