The universe is non-static. It is expanding due to the presence of dark energy.
Dark energy exert repulsive forces.
Then if we consider the sun and the Earth, is the locus of the Earth around the sun static or non-static? Is the Earth getting away from the sun?
As gravity of the sun acting on the Earth = centripetal force of locus of the Earth around the sun,
Can we determine the amount of dark energy by considering the gravity and the speed of the Earth?
