Tatooine

Tatooine is thought to have been one of the oldest planets in known space and was composed of a molten core with a rocky mantle and silicate rock crust. Other notable geological features included the Dune Sea, an enormous desert, Mushroom Mesa, a vast formation of giant standing stones, and the Jundland Wastes, a rocky region.

Because Tatooine orbits two suns, Tatoo I and Tatoo II, the planet is covered in deserts and rock formations, while the days are extremely arid and bright, especially during double noon. In fact, it is so brightly lit by the suns from space it could appear to be a star itself. This was the case for the people who discovered Tatooine as they first thought Tatooine was in fact a star until they approached and discovered that it was a desert planet. Due to the extreme conditions, only a relatively mild region of its northern hemisphere was habitable.
