title: Gravity field of jupiter from pioneer 11 tracking data.
abstract: Significantly improved values of the zonal gravity harmonic coefficients J(39) J(4), and J(6) of Jupiter have been obtained from a preliminary analysis of Pioneer 11 spacecraft Doppler data taken while the spacecraft was near Jupiter. The new results, which will have an important application as boundary conditions for theoretical models of Jupiter's interior. are consistent with a planet in hydrostatic equilibrium.
