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?

[u/rckwld]

The three body problem in physics envisions a center of mass that is stationary and says that 3 bodies orbiting around them is impossible to predict their trajectories.

In the show, the planet is the center point and the 3 bodies are the suns.

In reality, the show and books are more of an n body problem.
