Four planets, A through D, orbit the same star. The relative masses and distances from the start for each planet are shown in the table. For example, Plant A has twice the mass of Planet B, and Planet D has three times the orbital radius of Planet A. Which planet has the highest gravitational attraction to the star and why?
Planet A, relative mass is 2m, relative distance is r
Planet B, relative mass is m, relative distance is 0.1 r
Planet C, relative mass is 0.5m, relative distance is 2 r
Planet D, relative mass is 4m, relative distance is 3 r

A resonance orbit is one in which planets have a fixed ratio of orbital periods. For example, for 2 planets with an orbital resonance of 3:1, the outer planet's orbital period would be 3 times that of the inner one. That is, the inner planet can complete 3 exact orbits whilst the outer one completes only one. This is a special type of orbital "locking". The two planets orbiting the nearby star are observed to be in a 2:1 resonance...
