No force is necessary to cause orbital motion.
The planets orbit the sun (( roughly the center of
the effective mass (M-m) of the rest of the
universe )) at a special mean orbital radius to
conserve total energy.

Orbital motion has nothing to do with a force of
gravity. obrital motion obeys the first law of
thermodynamics, which says that the total
energy of the universe is a constant.
orbiting m***** have kinetic and potential
energies.
All of the planets and moons orbit at
nearly equal amounts of kinetic and potential
energies.
Any orbiting mass, m, such as the earth,
has a kinetic energy m (2 pi L )^2 / t^2
because of its velocity ,v , as m v^2 , and
a potential energy G ( M-m ) m / L,
because of its orbital radius L and the product
of the mases m and the rest of the effective
mass of the universe M-m, where M is the
effective mass of the total universe. In the
solar system this mass M would effectively
be the sum of the m***** of the sun and
the rest of the m***** of the planets of the
solar system.
The sum of kinetic and potential energies
would be a constant for any particular planet,
and any positive change of kinetic energy
would have to equal a negative change of
the potential energy, to conform with the
first law of thermodynamics.
No force or source of an energy change
is available to the orbiting mass ( if it is not in
contact with another mass ) , so it continues
to orbit at nearly the same radial distance from
the center of the mass of the rest of the
effective universe. All of the planets and moons
were found to orbit in this manner,
thus confirming the im****tance of the modified
first law of thermodynamics, as the fundamental
equation of the universe.
