  • It’s because the center of mass between the earth and moon is off center, nearly 3k miles from the core, and constantly moving as the moon orbits.

    So it’s not due to a direct pull upwards alone, and the earth’s orbit around the sun technically has a slight wobble due to it.

    Edit: For more info, look up info on the barycenter of the earth and moon.
