Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass. The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other increases, the force of gravity decreases. If the distance is doubled, the force of gravity is one-fourth as strong as before. It extends as far away in light-years as the earth is old. And farther, if you include the various things that eventually coalesced into the earth. So the earth's gravitational field is approximately a sphere about 4.5 billion light-years in radius.
