'''Callisto''' ''(kə-lis'-toe,'' {{IPA2|kəˈlɪstoʊ}}; Greek ''Καλλιστώ)'' is a [[natural satellite|moon]] of the [[planet]] [[Jupiter (planet)|Jupiter]], discovered in [[1610]] by [[Galileo Galilei]]. It is the third-largest moon in the [[solar system]], about 99% the size of the planet [[Mercury (planet)|Mercury]] but much less massive.

Although the name "Callisto" was suggested by [[Simon Marius]] soon after the moon's discovery, this name and the names of the other [[Galilean moons|Galilean satellites]] fell into disfavour for a considerable time, and were not revived in common use until the mid-[[20th century]]. In much of the earlier astronomical literature, Callisto is simply referred to by its Roman numeral designation, '''Jupiter IV''' or as "the fourth satellite of Jupiter".
+
'''Callisto''' is the outermost of [[Jupiter|Jupiter's]] four [[Galilean Moons]], and has been a part of [[Orbiter]] since it was added in Orbiter 2002. Callisto is the second largest moon of Jupiter just behind [[Ganymede]], and is the third largest moon after Ganymede and [[Titan]]. And Callisto is just about the same size as the planet [[Mercury]]. Callisto was discovered independently by [[w:Simon Marius]] and [[w:Galileo Galilei]] in 1610, Marius having seen it slightly before Galileo, and the name given by Marius is the one that we use today.
  
In scientific writing, the [[adjective|adjectival form]] of the name is usually ''Callistoan''.
+
== Callisto in Orbiter ==
 +
Callisto joined Orbiter with the release of Orbiter 2002. At that time its orbit was governed by the Callisto.cfg file, then governed by Vsop87.dll file at the release of Orbiter 2005.  
  
==Physical characteristics==
+
The orbit of Callisto is not locked into an orbital resonance with [[Io]], [[Europa]], and [[Ganymede]], which are in a 1:2:4 resonance. It revolves about 1.88×10<sup>6</sup> kilometers from Jupiter, eccentricity of 0.0074, and an inclination of about 0.25°. The moon has a mass of 1.08×10<sup>23</sup> kilograms and a radius of about 2.4×10<sup>6</sup> km.
[[Image:PIA01478 Interior of Callisto.jpg|thumb|left|120px|Interior of Callisto]]
 
===Internal Structure===
 
Callisto's battered surface lies on top of an icy layer that is about 150 kilometers thick. A salty [[ocean]] in excess of 10 kilometers thick may lay beneath the crust. Its presence is indicated by studies of the [[magnetic field]]s around Jupiter and its moons. It was found that the Callistoan magnetic field varies (flows in various directions at different times) in response to the background magnetic field generated by Jupiter; this suggests a layer of highly conductive fluid within the moon.  
 
  
Beneath the ocean, Callisto seems to have a strange interior that is not entirely uniform but does not vary dramatically. ''[[Galileo spacecraft|Galileo]]'' orbiter data suggest that the interior is composed of compressed rock and ice, with the amount of rock increasing with depth due to partial settling of its constituents. Callisto has the lowest density of the four Galilean moons of Jupiter, only 1.86 g/cm³, and is about 40% ice and 60% [[Rock (geology)|rock]]/[[iron]].

===Surface Features===
+
{{JupiterSat}}
Callisto is one of the most heavily cratered moons in the solar system. In fact, impact craters and associated concentric rings are about the only features to be found; there are no large callistoan mountains. This is probably due to the icy nature of its surface, with the largest craters and mountains being erased by the flow of the icy crust over geological time. Two enormous concentric ring impact basins are found on Callisto; [[Valhalla (crater)|Valhalla]] is the largest with a bright central region that is 600 kilometers in diameter and rings extending to 3000 kilometers in diameter, and the second-largest impact basin is [[Asgard (crater)|Asgard]] measuring about 1600 kilometers in diameter. Another interesting feature is [[Gipul Catena]], a long series of impact craters lined up in a straight line across Callisto's surface. This was probably caused by an object that was tidally disrupted as it passed close to Jupiter (much like [[Comet Shoemaker-Levy 9]]) before it impacted. Callisto's crust is thought to be approximately 4 billion years old, dating back almost to the formation of the [[solar system]].
+
{{SolarSystem}}
 
 
Unlike neighbouring [[Ganymede (moon)|Ganymede]] with its tectonic grooved terrain, there is little evidence of [[plate tectonics|tectonic]] activity on Callisto. While Callisto is very similar in bulk properties to Ganymede, it apparently has a much simpler geological history. The different geologic histories of the two has been an important problem for planetary scientists. "Simple" Callisto is a good reference for comparison with other more complex worlds.
 
 
 
===Atmosphere===
 
Callisto has a very tenuous atmosphere composed of [[carbon dioxide]]<ref name=calliatm>"[http://www.jpl.nasa.gov/releases/99/calliatm.html Galileo spacecraft finds thin atmosphere on Callisto]". Retrieved December 14, 2006.</ref>. Because such a thin atmosphere can easily be lost in a variety of ways ''(see [[atmospheric escape]])'', scientists believe that it is constantly replenished, possibly by slow sublimation of carbon dioxide ice from the satellite's icy crust.

Callisto is the outermost of Jupiter's four Galilean Moons, and has been a part of Orbiter since it was added in Orbiter 2002. Callisto is the second largest moon of Jupiter just behind Ganymede, and is the third largest moon after Ganymede and Titan. And Callisto is just about the same size as the planet Mercury. Callisto was discovered independently by w:Simon Marius and w:Galileo Galilei in 1610, Marius having seen it slightly before Galileo, and the name given by Marius is the one that we use today.

Callisto in Orbiter

Callisto joined Orbiter with the release of Orbiter 2002. At that time its orbit was governed by the Callisto.cfg file, then governed by Vsop87.dll file at the release of Orbiter 2005.

The orbit of Callisto is not locked into an orbital resonance with Io, Europa, and Ganymede, which are in a 1:2:4 resonance. It revolves about 1.88×106 kilometers from Jupiter, eccentricity of 0.0074, and an inclination of about 0.25°. The moon has a mass of 1.08×1023 kilograms and a radius of about 2.4×106 km.
