The extreme albedo asymmetry of Saturns moon Iapetus which is about 10 times as bright on its trailing hemisphere as on its leading hemisphere has been an enigma for three centuries. As one of the primal gods he was a brother to Cronus Saturn and the uncle of Zeus.

Because Iapetus doesnt rotate with respect to Saturn the same face continually catches the dark moon flakes.
. This made Iapetus difficult to spot as it mysteriously became brighter and fainter as it completed its orbit of Saturn. There seems to be a. The icy moon is often described as the most scientifically compelling place in our Solar System.
The leading hemisphere is as dark as a freshly tarred street and the white trailing hemisphere resembles freshly fallen snow. TF The leading hemisphere of Iapetus is much darker than the back side which is icy. Hal Levison a planetary scientist at the Southwest Research Institute in Boulder Colorado is talking about Iapetus the the third largest of the more than 60 moons of the planet Saturn.
Saturns walnut-shaped two-toned moon Iapetus. From Iapetus Saturn would appear to be 156 in diameter four times the size of the Moon viewed from Earth. Additional dark material is then slowly added to the leading hemisphere centered at 90.
Iapetus is the 23rd moon of Saturn and the seventh and outermost major moon. According to the story the dark side of the moon is almost perfectly bisected by a tall narrow ridge that runs for 1300 km 808 mi and rises up to 20 km 12 mi high. Deposition of exogenic dark material on the leading side has been proposed as a cause but this alone cannot explain the global shape sharpness and complexity of the transition between.
The leading edge in Clarkes words was about as light as burnt toast. From the other inner moons the rings would be edge-on and difficult to see. Iapetus is tidally locked to Saturn the same side is always facing the planet despite the distance from its mother planet.
The low density of Iapetus indicates that it is mostly composed of ice with only about 20 of rocky materials. Epimetheuss orbit is co-orbital with that of JanusJanuss mean orbital radius from Saturn is as of 2006 as shown by green color in the adjacent picture only 50 km less than that of Epimetheus a distance smaller than either moons mean radius. However after the heavenly battle called the Titanomachy he was banished to Tartarus the Greek place of punishment primarily reserved.
Iapetus is a two-toned moon. The ridge is around 13km 8 miles high in some places - taller than Mount Everest. TF Most of the moons of Saturn have rocky cratered surfaces like Deimos and Phobos.
Weve seen avalanches on Mars but now scientists have found avalanches taking place on an unlikely place in our solar system. Like our own moon Iapetus is in a near perfect circular orbit and one side always faces its planetary host. Because of this distant inclined orbit Iapetus is the only large moon from which the rings of Saturn would be clearly visible.
Saturns largest moon is named Titan and is larger than the planet Mercury. Myths of the Moons. This series of maps of Saturns moon Iapetus shows how a computer model of migrating ice can explain most.
Yin-Yang of Saturns Odd Moon Explained. Which space mission orbited Jupiter and dropped a probe into Jupiters atmosphere. The Cassini spacecrafts flyby of Saturns moon Iapetus has revealed a bizarre geological feature in its images.
The rings of Saturn are created from and controlled by the planets moons. Believe writes In another unexpected find by Cassini-Huygens Saturns moon Iapetus shows a bulging waistline. And these aren146.
Or in the words of a NASA press release 2. Having a very reflective icy surface that is heavily cratered. Iapetus is a world of contrasts and not just in terms of its color.
Iapetus is probably one of the most striking bodies in the solar system and one. Mission scientists have started to release detailed images of the moons surface which is sharply divided into a bright half and a dark half. Iapetus shown here is Saturns 3rd largest moon and known for its hemispheres of extreme contrasts of brightness and darkness.
The wind speeds found in the bands and. While Jupiter and Saturn may be mostly composed of liquid and gas they each do have a thin crustal layer that acts like plastic. Saturns second largest moon might best be described as.
This series of maps of Saturns moon Iapetus shows how a computer model of migrating ice can explain most features of Iapetus global appearance. In accordance with Keplers laws of planetary motion the closer orbit is completed more quickly. But even more puzzling are square and hexagonal craters that according to one former NASA employee appear to be gigantic artificial plants holding the moon together making Iapetus resemble nothing so much as the Death Star in George Lucass film Star Wars.
McKinnon said ice provides the best answer to that question. A bulging ridge at its equator. This height is a.
The model starts with Iapetus uniformly covered in ice with some dark material mixed in as shown in the top map. In addition it is a very small moon that still managed to be massive enough to achieve hydrostatic equilibrium. Iapetus Saturn The Greek Titan Iapetus is probably remembered more for the actions of sons than his own mythos.
Its orbital radius around Saturn is about nine times the distance between the Earth and Moon but is still. Because of the small.
