      Pull on the sun from what? to get the gravitational pull (I assume you mean force here) you need the mass of the two objects in question, and their distance:
      Take the mass of the sun (2×10^(30) kg), multiply by the mass of what ever you have in mind (in kg), multiply by 6.7×10^(-11), and divide that total by the distance between the sun and the thing you have in mind (distance Sun-Earth for example is ~ 150 billion meters). That will give you the force between them, the pull, due to gravity.
