All objects are attracted to the earth, and the direction of that force is towards the centre of the earth. Mass of the Earth = 5.98 \times 10^{24} \; kg Radius of Earth = 6378100 \; m G = 6.6726 \times 10^{-11} \; N-m^2/kg^2 Mass of Pluto/Mass of Earth = 0.021 Radius of Pluto/Radius of Earth = 0.187, If a planet has 2 times the radius of the Earth and 8 times the mass, what is the gravitational acceleration at the surface of the planet? The surface gravity may be thought of as the acceleration due to gravity experienced by a . The mass of Venus is 81.5% that of the earth, and its radius is 94.9% that of the earth. A planet has a mass of 5.30 x 10^{23} kg and a radius of 3.37 x 10^6 m. a. Thus, the value of g on the Earth is g=9.8m/s 2. 6. Do you need underlay for laminate flooring on concrete?
