Webb8 juli 2008 · The number of stars that are known to have debris disks is greater than that of stars known to harbour planets. These disks are detected because dust is created in the destruction of planetesimals in the disks much in the same way that dust is produced in the asteroid belt and Kuiper belt in the solar system. For the nearest stars the structure of … WebbFig. 3.1 illustrates three important characteristics of the Solar System: (1) the distribution of its objects over nearly three orders of magnitude of distance from the Sun (from a fraction of an Astronomical Unit (AU) to more than 100 AU), with the small terrestrial planets grouped near the Sun, the giant planets grouped outside, and several …
