| 9 | + <Description>Callisto is the outermost of the four Galilean moons of Jupiter. | |
| 10 | + It orbits at a distance of approximately 26 radius of Jupiter. | |
| 11 | + This is significantly larger than the orbital radius of the next-closest Galilean satellite, Ganymede. | |
| 12 | + 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 | |
| 13 | + and probably never has. | |
| 14 | + | |
| 15 | +Like most other regular planetary moons, Callisto's rotation is locked to be synchronous with | |
| 16 | +its orbit. The length of Callisto's day, simultaneously its orbital period, is about 16.7 Earth days. | |
| 17 | +Its orbit is very slightly eccentric and inclined to the Jovian equator, with the eccentricity and inclination | |
| 18 | +changing quasi-periodically due to solar and planetary gravitational perturbations on a timescale of centuries. | |
| 19 | +The ranges of change are 0.0072–0.0076 and 0.20–0.60°, respectively. | |
| 20 | +These orbital variations cause the axial tilt to vary between 0.4 and 1.6°. | |
| 21 | + | |
| 22 | +The dynamical isolation of Callisto means that it has never been appreciably tidally heated, | |
| 23 | +which has important consequences for its internal structure and evolution. Its distance from | |
| 24 | +Jupiter also means that the charged-particle flux from Jupiter's magnetosphere at its surface | |
| 25 | +is relatively low about 300 times lower than, for example, that at Europa. | |
| 26 | +Hence, unlike the other Galilean moons, charged-particle irradiation has had a relatively minor effect on Callisto's surface. | |
| 27 | +The radiation level at Callisto's surface is equivalent to a dose of about 0.01 rem (0.1 mSv) per day, which is over ten times higher than Earth's average background radiation.</Description> | |

| 8 | + <ReleaseDate>2018-10-14T11:46:29Z</ReleaseDate> | |
| 9 | + <Description>Europa orbits Jupiter in just over three and a half days, | |
| 10 | + with an orbital radius of about 670,900 km. With an eccentricity of only | |
| 11 | + 0.009, the orbit itself is nearly circular, and the orbital inclination | |
| 12 | + relative to Jupiter's equatorial plane is small, at 0.470°. | |
| 13 | + Like its fellow Galilean satellites, Europa is tidally locked to Jupiter, | |
| 14 | + with one hemisphere of Europa constantly facing Jupiter. Because of this, | |
| 15 | + there is a sub-Jovian point on Europa's surface, from which Jupiter would | |
| 16 | + appear to hang directly overhead. Europa's prime meridian is the line | |
| 17 | + intersecting this point. Research suggests that the tidal locking may not be | |
| 18 | + full, as a non-synchronous rotation has been proposed: Europa spins faster | |
| 19 | + than it orbits, or at least did so in the past. | |
| 20 | + This suggests an asymmetry in internal mass distribution and that a layer of | |
| 21 | + subsurface liquid separates the icy crust from the rocky interior. | |
| 22 | + | |
| 23 | +The slight eccentricity of Europa's orbit, maintained by the gravitational disturbances from | |
| 24 | +the other Galileans, causes Europa's sub-Jovian point to oscillate around a mean position. | |
| 25 | +As Europa comes slightly nearer to Jupiter, Jupiter's gravitational attraction increases, | |
| 26 | +causing Europa to elongate towards and away from it. As Europa moves slightly away from | |
| 27 | +Jupiter, Jupiter's gravitational force decreases, causing Europa to relax back into a more | |
| 28 | +spherical shape, and creating tides in its ocean. The orbital eccentricity of Europa is | |
| 29 | +continuously pumped by its mean-motion resonance with Io. | |
| 30 | +Thus, the tidal flexing kneads Europa's interior and gives it a source of heat, possibly | |
| 31 | +allowing its ocean to stay liquid while driving subsurface geological processes. | |
| 32 | +The ultimate source of this energy is Jupiter's rotation, which is tapped by Io | |
| 33 | +through the tides it raises on Jupiter and is transferred to Europa and Ganymede by the | |
| 34 | +orbital resonance.</Description> | |

| 9 | + <Description>Ganymede orbits Jupiter at a distance of 1,070,400 km, third among the Galilean satellites, | |
| 10 | + and completes a revolution every seven days and three hours. Like most known moons, | |
| 11 | + Ganymede is tidally locked, with one side always facing toward the planet, hence its day is | |
| 12 | + seven days and three hours. Its orbit is very slightly eccentric and inclined to the Jovian | |
| 13 | + equator, with the eccentricity and inclination changing quasi-periodically due to solar and | |
| 14 | + planetary gravitational perturbations on a timescale of centuries. | |
| 15 | + The ranges of change are 0.0009–0.0022 and 0.05–0.32°, respectively. | |
| 16 | + These orbital variations cause the axial tilt to vary between 0 and 0.33°. | |
| 17 | + | |
| 18 | +Ganymede participates in orbital resonances with Europa and Io: for every orbit of Ganymede, | |
| 19 | +Europa orbits twice and Io orbits four times. The superior conjunction between Io and Europa | |
| 20 | +always occurs when Io is at periapsis and Europa at apoapsis. | |
| 21 | +The superior conjunction between Europa and Ganymede occurs when Europa is at periapsis. | |
| 22 | +The longitudes of the Io–Europa and Europa–Ganymede conjunctions change with the same rate, | |
| 23 | +making triple conjunctions impossible. Such a complicated resonance is called the Laplace | |
| 24 | +resonance. </Description> | |

| 9 | + <Description>Io orbits Jupiter at a distance of 421,700 km from Jupiter's center and 350,000 km from its cloudtops. It is the innermost of the Galilean satellites of Jupiter, its orbit lying between those of Thebe and Europa. | |
| 10 | + | |
| 11 | + Including Jupiter's inner satellites, Io is the fifth moon out from Jupiter. It takes Io about 42.5 hours to complete one orbit around Jupiter. Io is in a 2:1 mean-motion orbital resonance with Europa and a 4:1 mean-motion orbital resonance with Ganymede, completing two orbits of Jupiter for every one orbit completed by Europa, and four orbits for every one completed by Ganymede. This resonance helps maintain Io's orbital eccentricity (0.0041), which in turn provides the primary heating source for its geologic activity. Without this forced eccentricity, Io's orbit would circularize through tidal dissipation, leading to a geologically less active world. | |
| 12 | + | |
| 13 | +Like the other Galilean satellites and the Moon, Io rotates synchronously with its orbital | |
| 14 | +period, keeping one face nearly pointed toward Jupiter. This synchronicity provides the | |
| 15 | +definition for Io's longitude system. Io's prime meridian intersects the equator at the | |
| 16 | +sub-Jovian point. The side of Io that always faces Jupiter is known as the subjovian | |
| 17 | +hemisphere, whereas the side that always faces away is known as the antijovian hemisphere. | |
| 18 | +The side of Io that always faces in the direction that Io travels in its orbit is known as | |
| 19 | +the leading hemisphere, whereas the side that always faces in the opposite direction is known | |
| 20 | +as the trailing hemisphere.</Description> | |
