There are many ideas floating around out there, about the planet Saturn. Claims that Saturn was once our Sun, or that the Earth was at one time a satellite of Saturn.
The name, Immanuel Velikovsky is often quoted in connection with these ideas. Here is a link which might be of some assistance to those who are interested in these matters. Also, is there any veracity in the idea that Mars was once a satellite of the (now exploded) planet, Phaeton?
