Constraints from density (green), D/I (blue) and CONSERT (red), and possible domain of volume ratio (yellow triangle) for a mixture of 75% organics / 25% silicates in volume. Only the upper quarter of the ternary diagram is plotted (porosity higher than 50%). The black diamond corresponds to a mixture of 30% ice, 10% dust, and 60% porosity.
