Riedt's Fc=Fg, a=Fc/mpl and mpl=Fg/a

The Centripetal force discovered by Huygens in 1659 is Fc = mpl*v^2/r.

The Gravitational force, after Cavendish discovered in 1798
the gravitational constant G, is Fg=G*(M*m/r^2).

The second law of motion ascribed to Newton is F = ma, a=F/m, m=F/a.

The nine major solar planets connect the different formulas of Huygens,
Cavendish and Newton by Fc=Fg; a=Fc/mpl and mpl=Fg/a:

Only if you approximate the orbits by circles.

As only circular orbits have a single speed value,
and only for circular orbits is gravitation force centripetal,
i.e. perpendicular to motion.
