Perihelion Shift of Mercury (クリ)
Size of Mercury will increase gravity and increase centrifugal force quolitatively also. Of the two, gravity is probably the main factor. Because, increase in gravity shift aphelion in the direction of revolution. On the other hand, increase in centrifugal force shift aphelion in the opposite direction of revolution.
The formula for gravity F = mM/r^2 probably shows that magnitude of gravity is related to the size of Mercury (but surprisingly small).
