Unlike the planets in the Solar System, Thurio is one of many planets that does not orbit around Sun and instead orbits a different kind of star and according to Admirals Watson and Crick, this planet is icy and cold. In fact, the entire planet is completely of ice.
When the Tomorrowland Transit Authority's rover froze on the surface while taking measurements, the Callistos journeyed to Thurio to retrieve it where they found the planet to be extremely icy and slippery. Loretta discovered the planet had rivers that flow with some kind of purple salt liquid. She fell into trouble when she got trapped on an iceberg, heading straight for a water fall. Luckily she was saved by Miles and her parents who got her to zip-line back to dry land.
