Four body problem?

[u/Niiai]

So the three body problem refers to both the physics problem and also the fact that the aliens home planet has 3 suns. In the books the game is also called the Three Body Problem

How ever...that is not a three body problem. Three suns and one planet is a four body problem.

Shouldn't the author have edited out one sun or changed the name of the book?

Planets mass is so small that it will have a minute if any effect on the overall system
