According to Einstein's theories, as anything having a mass in the universe, the Sun bends space-time basically in two ways (as far as I've understood) : by stretching it towards its center of gravity, and by dragging it along the direction of its rotation (Lense-Thirring / frame-dragging). Basically, it means that flying towards a massive celestial body (planet, star...) will increase your speed and dilate time, and if the mass is extreme (black hole / cf. "Interstellar" movie), it will strech your body ("spaghettification") and somehow send your "slender-self" in the future of the universe.
The gravitational field of the Sun extends far beyond the limits of the solar system, up to 1 light-year, that is 2104 times the distance between the Sun and Neptune, the closest star, Proxima Centauri, being located at 4,2 ly from the Sun.
