G is the gravitational constant and it is a very small number per kilogram of mass (6.67x10^-11 m^3/kg * s^2) but it adds up. The reason the sun doesn't collapse now is because the thermal pressure due to fusion perfectly counterbalances the suns gravitational mass. When the sun does finally burns up its fuel and collapses it will end up a stable object whose further collapse will be stopped by electron degeneracy pressure (look up the Pauli exclusion principle which also applies to neutron degeneracy pressure).
