Yes it get weaker because it depends upon the inverse of the square of the distance (or separation).

#### Explanation:

The gravitational force between two objects of mass ${m}_{1}$ and ${m}_{2}$ separated by a distance $r$ is given as:

${F}_{\text{grav}} = G \frac{{m}_{1} \cdot {m}_{2}}{r} ^ 2$

Where $G$ is the Universal Gravitational Constant$= 6.67 \times {10}^{-} 11 \frac{N {m}^{2}}{k {g}^{2}}$
