The largest impact crater on Callisto is known as Valhalla. It is 2, miles 4, km in diameter. Another large crater, Asgard, has a diameter of miles 1, km.
It appears that Callisto's surface has undergone very little change since its formation over four billion years ago. Because its surface is so geologically inactive, astronomers believe that Callisto may represent what many of the moons in the Solar System may have looked like at a much earlier stage in their development.
Composite image of the surface of Callisto showing large impact craters. The large, bright crater on the left is known as Asgard.
The white material is believed to be ice that was excavated by the impact. Callisto is very different from other rocky moons in the Solar System.
There are no mountains on Callisto. Astronomers believe this to be a result of movement in its icy surface. The entire surface of Callisto is covered with craters.
The largest craters have concentric rings that look like huge cracks in the surface. These rings may have formed when water beneath the crust leaked through to the surface.
Like Ganymede, Callisto's craters have been smoothed out by the flow of its icy crust. The craters lack the ringed mountains and central depressions that characterize craters on Mercury and the Moon.
One very interesting feature is known as Gipul Catena. This is a long series of craters arranged in a nearly straight line.
This was likely caused by an object that was broken into several pieces by tidal forces before it impacted the surface.
Planets Quiz Coloring Pages. Jupiter is the giant of the Solar System and has something like 50 or more satellites. A satellite is something that orbits around a body in space.
Of these satellites, or moons, there are about 16 large ones. The four largest are known as the Galilean moons because they were first seen and described by the great Italian scientist Galileo in They were later named Io , Europa , Ganymede and Callisto.
These moons were not known before because they cannot be seen with the naked eye. Galileo was the first person to design a telescope and was using this to examine the night sky.
The discovery of Callisto and the other 3 Galilean moons was extremely important. Galileo showed that these moons orbited round the planet Jupiter.
This later gave support to the new theory at that time that the planets of the Solar System orbited round the Sun. It is the 3rd largest moon in the Solar System , with a diameter of 2, miles 4, kilometres.
Callisto is larger than the planet Pluto and almost as big as the planet Mercury. Although it is the size of a small planet , Callisto is called a moon because it orbits round Jupiter and not round the Sun, as the planets do.
Callisto may be one of the oldest bodies in the Solar System. The surface of Callisto, showing ancient craters Callisto is more cratered than any other moon or planet in the Solar System.Rechtliche Hinweise lesen Ich habe die Nutzungsbedingungen gelesen und stimme ihnen zu.

Callisto moon -There is also a Jupiter Moons Tool which shows the positions of Jupiter 's four largest moons as a function of time. Payload accommodation would take into account the need for radiation shielding and satisfy requirements from individual instruments. Callisto 's interior is probably not differentiated into a rocky core surrounded by lighter icy material, like that of the other three large moons of Jupiter -Io, Europa, and Ganymede. Which of these three would most likely survive in the extreme environment of the Jupiter moon Callisto , and why? The main spacecraft design drivers are related to the large distance to the Sun, the use of solar power generation, and Jupiter's harsh radiation environment.

In much of the earlier astronomical literature, Callisto is referred to by its Roman numeral designation, a system introduced by Galileo, as Jupiter IV or as "the fourth satellite of Jupiter".
IPAc-en , or Callistan. Callisto is the outermost of the four Galilean moons of Jupiter. As a result of this relatively distant orbit, Callisto does not participate in the mean-motion resonance —in which the three inner Galilean satellites are locked—and probably never has.
Like most other regular planetary moons, Callisto's rotation is locked to be synchronous with its orbit. Its orbit is very slightly eccentric and inclined to the Jovian equator, with the eccentricity and inclination changing quasi-periodically due to solar and planetary gravitational perturbations on a timescale of centuries.
The ranges of change are 0. The dynamical isolation of Callisto means that it has never been appreciably tidally heated , which has important consequences for its internal structure and evolution.
Hence, unlike the other Galilean moons, charged-particle irradiation has had a relatively minor effect on Callisto's surface.
Size comparison of Earth , Moon and Callisto. The average density of Callisto, 1. The weight ratio of iron to silicon is 0.
Near-infrared spectroscopy has revealed the presence of water ice absorption bands at wavelengths of 1. Small, bright patches of pure water ice are intermixed with patches of a rock—ice mixture and extended dark areas made of a non-ice material.
The Callistoan surface is asymmetric: This is different from other Galilean satellites , where the reverse is true. Model of Callisto's internal structure showing a surface ice layer, a possible liquid water layer, and an ice—rock interior.
Beneath the lithosphere and putative ocean, Callisto's interior appears to be neither entirely uniform nor particularly variable.
Galileo orbiter data  especially the dimensionless moment of inertia [lower-alpha 2] —0. The density and moment of inertia are compatible with the existence of a small silicate core in the center of Callisto.
Galileo image of cratered plains, illustrating the pervasive local smoothing of Callisto's surface. The ancient surface of Callisto is one of the most heavily cratered in the Solar System.
The large-scale geology is relatively simple; there are no large mountains on Callisto, volcanoes or other endogenic tectonic features.
Callisto's surface can be divided into several geologically different parts: The light plains include bright impact craters like Burr and Lofn , as well as the effaced remnants of old large craters called palimpsests , Template: Refn the central parts of multi-ring structures, and isolated patches in the cratered plains.
The bright, smooth plains constitute a small fraction of Callisto's surface and are found in the ridge and trough zones of the Valhalla and Asgard formations and as isolated spots in the cratered plains.
They were thought to be connected with endogenic activity, but the high-resolution Galileo images showed that the bright, smooth plains correlate with heavily fractured and knobby terrain and do not show any signs of resurfacing.
They are possible cryovolcanic deposits. Chains of secondary craters from formation of the more recent crater Tindr at upper right crosscut the terrain.
Impact crater diameters seen range from 0. These are unusually shallow and may be a transitional landform to the multi-ring structures, as with the Lofn impact feature.
The largest impact features on Callisto's surface are multi-ring basins. They were probably created by objects that were tidally disrupted as they passed close to Jupiter prior to the impact on Callisto, or by very oblique impacts.
Dark material usually lies in the lowlands surrounding and mantling bright features and appears to be smooth.
On a sub-kilometer scale the surface of Callisto is more degraded than the surfaces of other icy Galilean moons. The non-ice remnants form debris avalanches descending from the slopes of the crater walls.
The relative ages of the different surface units on Callisto can be determined from the density of impact craters on them. The older the surface, the denser the crater population.
Callisto has a very tenuous atmosphere composed of carbon dioxide. The surface pressure is estimated to be 7.
Callisto's ionosphere was first detected during Galileo flybys;  its high electron density of 7—17 Template: Hence, it is suspected that the atmosphere of Callisto is actually dominated by molecular oxygen in amounts 10— times greater than Template: Observations with the Hubble Space Telescope HST placed an upper limit on its possible concentration in the atmosphere, based on lack of detection, which is still compatible with the ionospheric measurements.
The partial differentiation of Callisto inferred e. The further evolution of Callisto after accretion was determined by the balance of the radioactive heating, cooling through thermal conduction near the surface, and solid state or subsolidus convection in the interior.
It is known to develop when the temperature is sufficiently close to the melting point , due to the temperature dependence of ice viscosity.
The basic ingredients for life—what we call 'pre-biotic chemistry'—are abundant in many solar system objects, such as comets, asteroids and icy moons.
Biologists believe liquid water and energy are then needed to actually support life, so it's exciting to find another place where we might have liquid water.
But, energy is another matter, and currently, Callisto's ocean is only being heated by radioactive elements, whereas Europa has tidal energy as well, from its greater proximity to Jupiter.
Based on the considerations mentioned above and on other scientific observations, it is thought that of all of Jupiter's moons, Europa has the greatest chance of supporting microbial life.
The Pioneer 10 and Pioneer 11 Jupiter encounters in the early s contributed little new information about Callisto in comparison with what was already known from Earth-based observations.
The target chosen to consider in detail was Callisto. The study proposed a possible surface base on Callisto that would produce rocket propellant for further exploration of the Solar System.
Such a base could facilitate remote exploration of Europa , or be an ideal location for a Jovian system waystation servicing spacecraft heading farther into the outer Solar System, using a gravity assist from a close flyby of Jupiter after departing Callisto.
