Although surface gravity of large planet is relatively small compared with small planet, gravitational force is large at distant position.

That is to say, gravitational acceleration of earth at r=2.626$ r_e $ is less than that of lunar surface.

To estimate surface gravity of the sun, equatorial centripetal acceleration has been calculated as 0.05903 m/$ s^2 $. The value is known lower limit of Surface gravity of the sun.
