| The_Schwam,
you are the only person who can help me! Can I ask you a question about GURPS?
I'm studying GURPS-Space in order to create believable star systems for a science-fiction novel.
The manual is very clear and I've already read the "errata corrige", but I am not sure if the third column, page 117, takes into account a situation where the planet is tide-locked to its moon but NOT to its star (Pluto is a great example: it is tide-locked to Caronte - it always shows the same face to Caronte -, but it is not tide-locked to the Sun).
In a Pluto-like situation, I should use the "Rotation Period Table", right? In fact, my "alien Pluto" is tide-locked to its moon but doesn't show always the same face to its star too. Right? But, since, as a rule, any planet tide-locked to something (the moon in this case) would have a Total Tide Effect =or>50, in my planetary Rotation Period calculations I should do: (number=or>50) + 3d + 10 (because the planet is a standard terrestrial) = a number surely >36, which implies the use of the following table, the Special Rotation Table.
Is this procedure correct?
I have doubts only because the way sentences are written in the paragraph make me think that the author hasn't kept this Pluto-like situation into account.
Grazie.
P.S.: I know it's a very specific question, but unfortunately there aren't many forums to ask this kind of doubts.
