How are conditions in Uranus's interior determined? Group of answer choices It is impossible to know anything about the interior of such a distant object. There were several spacecraft that were able to collect samples of Uranian material from all of its layers, and then mathematical models of Uranus's interior were built. The mass and radius can be measured based on observation, then the density is calculated. Based on the density and atmospheric spectra, mathematical models of Uranus's interior are built. The mass and radius of Uranus can be measured based on observation of its moons' motion, then their densities are calculated. Then scientists look for the materials on Earth that have exactly the same density as Uranus
