ah...the equations are beyond me (for now at least) but I'm giving it a go.
Sorry if I am off track, but I am endeavoring..
My question was "is there a physical reason why all bodies rotating under gravity enjoy the same relationship between T and r".
So every planet, or indeed anybody rotating [indeed moving] with constant acceleration has constant momentum.
The relationship between T and r is thus a determinant of the relationship between the gravitational constant, the body's momentum and the body's distance from the Sun.
This relationship between T and r is a constant value which is obeyed by all bodies rotating with constant acceleration.
Kepler's equations, the third in particular, are a mathematical calculation 'proving' that the relationship is a consequence of the foregoing.
So the relationship is a "universal" constant but one which, unlike the speed of life, has an underlying mathematical explanation.
Thank, hopefully Martyn
