Inside planets and the Sun
Probe a calculated rocky planet, or explore reference cutaways of the Sun and the four giant planets.
Try this
Open a rocky planet and change the core size and mantle density. Read the gravity profile and central pressure from the layered model.
The model and its limits
Two incompressible spherical layers in hydrostatic equilibrium. No equation of state, thermal evolution or seismic inversion. The colour bands are illustrative.
Equations used in the module
Equations M(r) = 4π ∫ρ(s)s²ds; g(r) = GM(r)/r²; P(r) = ∫[r,R] ρ(s)g(s)ds
