    force on pod proportional to mass of object/distance squared
mass of earth >>mass of moon
therefore distance from moon must be smaller to get same force magnitude from each.

    It is closer to the moon because the moon has less mass. For the two forces to be equal and opposite, you must have 
Mearth/Rearth^2 = Mmoon/Rmoon^2
Therefore Rearth/Rmoon
= sqrt(Mearth/Moon)
which is greater than 1
    
Mearth/Rearth^2 = Mmoon/Rmoon^2
Therefore Rearth/Rmoon
= sqrt(Mearth/Moon)
which is greater than 1
