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_("grav")=G(m_1*m_2)/r^2

Where G is the Universal Gravitational Constant=6.67xx10^-11 (Nm^2)/(kg^2)
