Answer» nothing will change. we will BECOME hotter after billions of years. we will be going around but not STRICTLY in closed orbits. after sufficiently long time we will leave the solar system. Solution :When `G` decreases with time, the gravitational force `F = (GM m)/(r^(2))` will become weaker with time. Then `r` increases with time. Due to it, EARTH willl be going around the SUN not strictly in closed orbit and after long time itwill leave the solar system.
