   No, it is NOT, as I just explained.

   The/Newton's gravitational constant is (written) "G", NOT "g":   
      
     G =~ 6.674 * 10^-11 m^3/(kg s^2).   
      
   (If one wants to do physics, one would be well to understand the difference   
   between a lowercase and an uppercase letter, and dimensional consistency.)   
      
   g is the gravitational _acceleration_ -- a different, but related quantity.   
   As I just explained.   
      
   In a nutshell:   
      
     F = m A = m g(r) = G M m/r^2 =: F_g  ==>  g(r) = G M/r^2 != const.
