The strength of the Sun's gravitational field depends on the distance from the Sun.


The Sun, and any other body, has a gravitational field. This field causes any other body to accelerate. Newton described this with his inverse square law and his second law force #F# equals mass #m# times acceleration #a#.



This says that the acceleration #a# due to gravity is independent of the mass of the body #m# under gravity. Where #GM = 132,712# is the gravitational constant multiplied by the mass of the Sun and #r# is the distance from the Sun.

General Relativity (GR) redefines gravity. It is not a force, it is a consequence of space time being curved by mass, energy and momentum. For relatively small masses, which includes the Sun, and low speeds GR reduces to Newton's laws.

Everything in a gravitational field experiences an acceleration towards the centre of the body causing the gravitational field. Everything follows a geodesic, which is the 4 dimensional equivalent of a straight line in curved space time.

So, the Sun doesn't exert a pull strength, it simply bends space time because of its mass and motion.
