The estimated mass and radius of Planet X are used to caleulate the minimum escape speed, Ve, for an object launched from the surface of the planet. If the actual mass and/or radius of the planet are slightly different from the estimated values, how will the actual escape speed Va for the surface of Planet X compare to ve ? v_a < v_c if the actual mass is the same as and the actual radius is less than their estimated values. v_a > v_c if the actual mass is less and the actual radius is greater than their estimated values. v_a > v_c if the actual mass is greater and the actual radius is less than their estimated values. v_a = v_c regardless of any difference in mass or radius. v_a < v_c if the actual mass is greater and the actual radius is the same as their estimated values.
