Satellite-size comparison with four planets in the solar system solar system all diameters greater than 400 km
Currently the total number of natural satellites of various types of celestial bodies in the solar system has been more than 180, and every year a new satellite to be discovered. These satellites in some large rocks rocky, and some of them are big hockey ice and rocks, and some satellite looked very strange, long like some Star Wars in the "Death Star" and some because the tidal heating stellar surface is extruded often move up and down meters. Photo below a solar system will show the most exotic five satellites.
Iapetus Saturn's moon may have the highest and lowest temperatures the Japanese side on the back surface temperature day; in the dark Cassini area near the equator, the endothermic effect of dark matter will cause its daytime temperature reached -145.15 ℃ while the average temperature bright highlands was -160.15 ℃.
Resulting in bright and dark sides of reasons: presumably because other neighboring small satellites since the bombardment of meteoroids formed on the surface caused by debris from entering the Iapetus orbit. During this period due to exposure to sunlight, after debris began to darken ice sublimation ingredient. While Iapetus is Saturn's tidal locking, these debris through the orbit of Iapetus, Iapetus is likely to be on the same side (the dark side) adsorption. This layer covers the dark side (Cassini region) adsorption was caused by a change Iapetus surface albedo, which in turn causes a change in temperature. Since Iapetus rotation period of up to 79 Earth days, the difference between the temperature of the ice means easier sublime dark areas, and eventually re-condenses highlights Heights. This action makes further darken Cassini area, Heights then becomes brighter.
Titan eight low density, possibly by the majority of ice and a small amount (about 20%) of the rock formations.
Equatorial ridge may be formed Titan remaining part of the initial eight flat spherical shape of stars, then its rotation is much faster than today. Early shortest period of rotation may only be 17 hours, but now take up to 79 days rotation period. Equatorial ridge terrain suffered heavy bombardment, which has proved very old geological ages. Such prominent equatorial terrain makes Titan was eight walnut-shaped appearance.
Equatorial ridge constituted by a variety of complex terrain, including separate peaks, the length of over 200 kilometers of cliffs and terrain unit consists of three parallel ridges close distance constituted. In the bright equatorial ridge Heights does not exist, instead it is a series of highly equatorial region of 10 kilometers separate peaks.

Iapetus's orbit slightly abnormal. It is the third largest moon of Saturn, Saturn's largest moon is farthest distance, while the rule in its satellite orbital inclination maximum; only the outer irregular satellites, such as Phoebe have a greater inclination orbit. The reason for this phenomenon is unknown.
Since the distance of Saturn reached 3.54 million km, is very remote and large orbital inclination, so Iapetus is the only one you can clearly see the rings of Saturn's largest moon; others are facing the inside edge of the large satellites of Saturn's rings, so it difficult observation to this configuration. Observations from the Iapetus, Saturn's perspective is four times observed on Earth the moon Perspective.
There are 400 active volcanoes on Io, the solar system's most active geological objects. Extreme geologic activity is the result of internal because Io by Jupiter and the other two Galileo satellites gravitational pull, causing tidal friction caused by internal heating.
Io due to the gravity of Jupiter and the other Galilean satellites of two dramatic tension, surface up and down movement of up to 100 meters, while the other two Galilean moons of Jupiter and tidal forces make the interior of Io constantly heated to form the surface of the volcano, Some volcanoes caused by sulfur and sulfur dioxide stream can climb to 500 km altitude, unlike most of the outer solar system satellites (they have covered with thick ice), Io has a core of molten iron or iron sulfide and silicate-based rock. Most of Io's surface is covered by sulfur and sulfur dioxide frost.
Standing on the surface of Jupiter Io is very spectacular, but the intensity of radiation within the range of depths Io orbits Jupiter, unprotected humans could not land its surface.
Io and Europa have a 2: 1 orbital resonance, and Ganymede has a 4: 1 orbital resonance that Io orbiting Jupiter every two weeks, that is orbiting Europa week; and Io Each bypass around Ganymede bypass week. This resonance assist Io maintain orbital eccentricity (0.0041), and in turn provide the main source of heat (tidal heating) is geologically active Io. No such relationship resonance orbit, Io's orbit by tidal dissipation will be rounded quickly become a less geologically active planet.
Hyperion lower density, surface like a sponge, known objects in the solar system rotation chaos of the largest objects, Saturn revolution around every 21.3 days, Hyperion may be the rest of the wreckage after a bigger satellite was hit.
Hyperion eccentricity orbit around Saturn is large and close to Saturn's largest moon Titan orbits, vulnerable to the combined effect of Saturn and Titan gravity. These factors together limited its rotation stable conditions.
Mimas relatively low density (1.17), may be caused by a lot of ice and a little rocky. Titan one of the solar system's smallest known so far to achieve hydrostatic equilibrium spherical objects. However, due to tidal action, Mimas was not perfectly spherical; the long axis of about 10% longer than its minor axis. From the recent Cassini sent back pictures of view Mimas closer oval.
The most notable feature of Mimas is a diameter of 130 kilometers of large craters - Herschel crater. Herschel crater diameter of approximately one-third the diameter of the satellite, its pit edge up to 5 kilometers, some 10 kilometers Bottom of the deep, and its central peak is higher than the bottom of the pit 6 km.
The formation of this crater impact event will Mimas almost disintegrated: the opposite side of the crater can still clearly see the broken terrain, which could be hit after Mimas stars across the shock wave caused.
Due to the existence of the big stars surface crater, Mimas even with "Star Wars" in the "Death Star" surprisingly similar, but this is only pure coincidence. Because Mimas first close-up pictures (1979) back to Earth three years ago (1976), "Death Star" shape had appeared in the "Star Wars" movies.
Miranda mostly ice, low-density silicates and organic compounds, the surface topography of complex chaotic show had intense geological activity on the satellite.
So far, only Voyager 2 visited Uranus and its moons. January 1986 Voyager on the 2nd Miranda flying over the southern hemisphere, shot it toward the side of the sun shine only close-ups, showing its geological activity Uranus was the most active.
Miranda believes in past geological activity orbital eccentricity than the current large, he had experienced tidal heating. Early Miranda and Umbriel may have a 3: 1 orbital resonance, only after departing from that state. Orbital eccentricity resonance will increase over time, tidal forces caused by the tidal friction generated Uranus, causing the satellite to be heated causing geologic activity inside Miranda's surface.
Miranda Verona in a spectacular cliff jump
Miranda has the highest cliff in the solar system: Cliff Verona (Verona Rupes), the cliffs high more than 5 kilometers, could reach 20 km deep. Miranda surface because of gravity only 0.079m / s2, thus jumped from the cliff top, after 12 minutes will reach the bottom of the cliff, but this time with your speed of about 200 kilometers per hour in a car quite. Before approaching the landing, just back a little rocket thrust reverser, you can surely face the local falls of the Miranda.
