Is there a simple mathematical relation between the speed at which the Earth spins and the magnitude of the frame-dragging effect?

Frame dragging and rotation, also known as the Lense-Thirring effect, is a phenomenon in which a rotating massive object, such as a planet or star, drags the space-time around it as it rotates. This effect is predicted by Einstein's theory of general relativity.
Frame dragging and rotation causes the space-time around a massive rotating object to twist, which in turn affects the motion of nearby objects. This effect is most prominent near the rotating object, and decreases as the distance from the object increases.
Yes, frame dragging and rotation has been observed on Earth using sensitive satellite measurements. In 2004, the Gravity Probe B mission confirmed the existence of frame dragging by measuring tiny changes in the orientation of gyroscopes in orbit around Earth.
Frame dragging and rotation has potential applications in space navigation, as it can be used to accurately determine the position and orientation of a spacecraft. It may also have implications for future technologies that rely on precise measurements of space-time, such as gravitational wave detectors.
No, frame dragging and rotation is just one aspect of how rotating objects affect space-time. Another effect, known as frame dragging precession, describes how the rotation of a massive object causes a change in the orientation of a nearby object's axis of rotation over time.
