Rotating masses drag along the space around them.
Frame dragging, in general relativity, is an effect on spacetime. It is a prediction of Albert Einstein's general theory of relativity.
Frame dragging is related to the rotation of masses.

Lense-Thirring effect
In 1918, the first frame dragging effect was derived by Josef Lense and Hans Thirring. Their idea was that the rotation of a massive object would be sufficient to distort the spacetime metric. The orbit of a nearby test particle would precess. This is different from Newtonian mechanics, where the gravitational field of the object does not depend on its rotation, only its mass. The Lense-Thirring effect is very small. It is about one part in a few trillion.
