What is Callisto surface made of?
What is Callisto surface made of?
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.
What kind of rock is Callisto made of?
Callisto is made of equal parts rock and iron and ice. The surface of the moon contains water ice, carbon dioxide ice, rock particles, silicate dust and hydrocarbon compounds.
Why is Callisto called the dead moon?
Callisto is a large moon orbiting Jupiter. It has an ancient, cratered surface, indicating that geological processes could be dead.
How was Callisto created?
Unlike Earth’s Moon which may have been a piece of Earth that broke away after an impact billions of years ago, Callisto is thought to have formed by slow accretion from the disk of the gas and dust that surrounded Jupiter after the planet was formed 4.5 billion years ago.
What is the oldest planet?
Jupiter formed less than 3 million years after the birth of the solar system, making it the eldest planet. Saturn formed shortly after, amassing less material since Jupiter gobbled such a large portion of the outer disk.
How thick is the ice on Callisto?
The Interior of Callisto Callisto is the most heavily cratered satellite in the solar system. Its battered surface lies on top of an icy layer (shown as a whitish band) that is about 200 kilometers (124 miles) thick.
Can you breathe 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.
Could there be life on Callisto?
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.
Why is Callisto so colorful?
Of Jupiter’s four largest moons, Callisto orbits farthest from the giant planet. Callisto’s surface is uniformly cratered but is not uniform in color or brightness. Scientists believe the brighter areas are mainly ice and the darker areas are highly eroded, ice-poor material.

Is there oxygen on Callisto?
Observations of Callisto’s leading/Jupiter-facing hemisphere show, for the first time, variable-strength atomic oxygen (O I) emissions with brightness up to 4.7 ± 0.7 Rayleighs for the O I 1304 Å triplet and 1.9 ± 0.4 Rayleighs for the O I 1356 Å doublet, averaged over the 2.5 arcsec.
Did Zeus and Callisto have a child?
Zeus then gave Arcas, his child with Callisto, to the Titaness Maia to raise. He then placed Callisto among the stars as the constellation Ursa Major (Great Bear).
Why did Callisto turned into a monster?
There is a possibility that Zeus has place a curse on Callisto; if she attempts to reveal the identity of their true father to Kratos and/or Deimos, she will transform into a mindless monster that will slay them.

Originally an Arcadian god of hills and woods, the protecting deity of flocks, herdsmen, and hunters; the son either of Hermes and a daughter of Dryops, or of Zeus and the Arcadian Nymph Callisto.

Is there a 100th planet?
Astronomers have announced the discovery of the 100th planet known to inhabit another solar system. The star is 100 light years from Earth in the southern constellation Grus, or The Crane. The planet, one and a half times the mass of Jupiter, has a roughly circular orbit, like those of the sun’s family of planets.
What planet has 47 moons?
The moons of Saturn are numerous and diverse, ranging from tiny moonlets only tens of meters across to enormous Titan, which is larger than the planet Mercury.
Can we breathe on Callisto?

Why is Callisto Brown?
Callisto’s surface is uniformly cratered but is not uniform in color or brightness. Scientists believe the brighter areas are mainly ice and the darker areas are highly eroded, ice-poor material.
What are Ganymede and Callisto made of?
Ganymede and Callisto are planet-sized moons of Jupiter, with surfaces composed of a mixture of dark dust and bright ice. Similar in size, they both have interiors of half ice and half rock/metal, but Ganymede’s interior appears to be segregated by density, while Callisto’s interior is mostly mixed.
