Document Summary
Has density at depth due to moment of inertia point. Small core 100km in diameter, made of iron or sulphur probably sulphur. Very thick atmosphere 500km thick: decays towards nothing no boundary to atmosphere. Higher pressure on surface of venus than earth. Thin crust temperature too hot b/c of radioactive decays that makes crust not molten. Very thin liquid iron layer in core 0-400km no magnetism. Surface rocks so hot that they don"t provide thick insulting layer on surface, heat escapes into hotter temperatures, allows venus to lose primordial heat much more rapidly than earth.
