One of Saturn's satellites, Phoebe, has the water Most unusual of the entire solar system, According to a new study by a group of scientists from the Planetary Science Institute in Tucson, Arizona.
In the framework of the work, researchers analyzed The isotopic ratios of deuterium (D / h) Of the rings and satellites of Saturn, which showed that all have a surprisingly similar water through its isotopic composition to the ground, with the exception of feebe.
The water in the satellite is more unusual than any other planet, says the article on Phys.org. Its isotopic composition shows that it is produced and Comes from a remote place From our solar system.
"The D / h ratio of fairy is the Maximum value Recalls that it has expressed itself in the cold and bound solar system, over Saturn, "explains Robert N. Clark, the leader of the work and researcher at the Institute of Planetary Sciences.
In the framework of the work, his team also measured The ratio of carbon 13 to carbon 12 (13C / 12C). The moon of Saturn, Yapetus, turned out to have the ratio similar to the terrestrial one, though it did Five times higher. Scientists point out that this also indicates that the satellite produced in the coldest ends of the solar system, much more than Saturn, and is subsequently captured & # 39; By an orbit of the second largest planet in the solar system.
The measurements were made remotely of the NASA Cassini probe using the visual and infrared mapping spectrometer (wimp). The study was published in Icarus on November 29, but was temporarily removed for reasons that the magazine did not explain.
