Where is the closest analog of Solar system?
« on: 16/10/2009 15:49:38 »
Trying to unravel the riddle of the origin of the solar system planetary scientists are looking for similar systems that are are being for thousands of light years away. Meanwhile, they ignore at least three analogues inside our own planetary system. This satellite systems of giant planets - Jupiter, Saturn, Uranus. Which of these systems is the most similar to the total solar system and why?

At first glance, these systems do not have any special fundamental differences from one another. Is that the Galilean moons of Jupiter denser than moons of Saturn or Uranus (Jupiter's moon Io is denser than our moon!). So the protomoonsí disk of Jupiter had a lot of stone and metal. Density of close satellites - Io and Europe is far exceeds the density of satellites - Ganymede and Callisto. And this fact also reminds the solar system - the division of the planets in two groups of giant planets and terrestrial planets. So the system of Jupiter, is the closest to the solar system?

However, if making such a logical conclusion, we make a big mistake. In fact, the closest analogue, of course, is the system of Saturn. And it is for following reason.

Among other satellites in the Saturnís system the Titan is distinctly allocated, as well as in the solar system the planets Jupiter is. Letís take their orbital radii  as the units of distance. Compare moons of Saturn, lying inside the orbit of Titan, with the terrestrial planets , (lying inside the orbit of Jupiter). Call attention to a pair of moons Dione-Tethys and Enceladus-Mimas. We associate the pair Enceladus-Mimas with the pair of planets Earth-Venus. And what can be associated with a pair Dione-Tethys?
