Free convection flow is heat transfer on fluid caused by buoyancy forces because of density difference. We further use The boundary layer theory to obtain governing equations. The governing equations are further transformed into non-dimensional and then transformed into the non-similar governing equation. The non-similar governing equations are solved numerically by using explicit finite difference method. The numerical results are analyzed correlation viscoelastic and Prandtl number with velocity and temperature profile. Based on the numerical results of free convection flow of viscoelastic fluid past over a sphere, we obtained that the velocity profile decreases when we apply the increasing in the values of viscoelastic and Prandtl number. The temperature profiles increases with the increasing in the values of viscoelastic, but decreases when the values of Prandtl number increases
