Never having watched any of the post-G1 shows (aside from a smattering of RID) or read any of the comics, I'm just curious about the planetary science behind ol' Cybertron... Does it orbit a star (or some other big gravitational mass) or is it just a free-floating asteroid? That seems odd, since it has (well, had) moons. How far away from Earth is it supposed to be? Is it supposed to be about Earth-size, or considerably smaller? When did the idea appear that it is the alt mode of Primus? Is that a pretty recent addition to the mythos, or has it been around for a while? If this has already been done to death in the past feel free to close this thread. Just a bored afternoon question from a TF newbie.
