How the Satellites Formed?
Assume that there is a large sand cloud in the space and in that there is the star sand are collapsing due to the gravitational force of the air in the space. In this stage they come closer to each other, the product capacity in this area is increased at the center of this area and becomes hot, and after certain stage, it is changed as a star center. In the meanwhile the area around this starts to rotate clockwise to one side and after this the completely sand cloud is changed into a form of a thin slate. This slate is called as Proto Panetory Disk. The material in this disk forms big in the course of the time. After some years they change as the planets. In the experiments that are conducted through the Hubble telescope, the scientists used to observe these stages. Around 25 stars are examined under the survey called, “The Space Telescope Imaging Spectrograph Chronographic Survey of Free Main Sequence Stars”. In this survey, it is observed that there is a thin layer of the slate for 7 stars and broad slates for two stars which are very brightful. The material in the bright slates is not formed in groups and through this survey; the scientists got an idea about the satellites and their formation. It is also observed that there are satellites on the other side of the solar family and they rotate round the bright stars through the Nebula.
