The next 2 questions refer to this scenario: Suppose we have discovered a new solar system, comparable to our own, orbiting the star Toon. It contains at least four planets (shown in the diagram—not necessarily in order or to scale). We have been able to obtain some of the information regarding this solar system: m = mass in units of Earth masses (Me) r = radius of planet in Earth radii (re) R = mean distance from center star in units of the Earth’s orbit’s radius (Re).
