WebThe gravitational constant G was first measured accurately by Henry Cavendish in 1798. He used an exquisitely sensitive balance to measure the force between two lead spheres whose centers were 0.29 m apart. One of the spheres had a mass of 158 kg, while the mass of the other sphere was 0.63 kg. WebThe formalism is applied to the Martian satellite Phobos. Based on a 3-dimensional shape model of Phobos by Duxbury, the gravitational coefficients up to degree and order 4 for a homogeneous Phobos are computed. In particular, we find J 2 = 0.105. WebThe most feasible parameter solution set consisted of the Phobos gravitational constant and the spacecraft initial conditions.
