The Earth experiences graviational pull from other stars!

Gravitational force, or gravity, is the mutual attraction between all masses in the universe. Most scientists assume that gravity travels at the speed of light, which is actually the propagation speed of electromagnetic waves (such as light) in a vacuum.

The assumption that gravity also travels at this speed is implicit in Einstein's general theory of relativity, formulated in 1915, which recognizes the universal character of the propagation speed of light and the consequent dependence of space, time, and other mechanical measurements on the motion of the observer performing the measurements.

Throughout this theories, among many others, we can determine that not only do we see distant stars as they were thousands of years ago, but we also still experience their gravity from thousands of years ago, and not from where they are now. We even experience the pull of gravity from stars that have burned out.
