The Science:

• The actual orbits of these 3 planets may be observed, but this is boring.

• One planet, say Earth, can be made more massive, in which case it will disrupt the other orbits, temporarily capturing other planets as satellites and/or ejecting them from the system.

• The sensitivity of this dynamical system, when one planet is massive, to the initial conditions (the big planet’s mass) has to be seen to be believed.
