Best described as "a large, hot ball of dust," Raisa is possibly the most inhospitable planet in the entire Alderaan system. Located in an orbit which regularly takes it close enough to the sun to completely strip its atmosphere, Raisa moves through space devoid of even the most minor layer of gas to shield it from interstellar radiation; as a result it is covered by a vast irradiated desert. No form of life can exist here without extensive technological support, and even that needs to take care where it settles. Due to the lack of atmosphere, Raisa is also vulnerable to periodic meteor strikes, with several areas having been struck repeatedly since the planet was first charted. Girdling the planet are several large volcanic mountain ranges which, if not for its orbit, would likely have provided Raisa with an atmosphere by now, but instead simply pump lava across the planets surface and add more layers to the yellow-grey dust to the deserts. Every so often a particularly violent eruption will spray material into low orbit, but eventually everything is pulled back to the surface by gravity, often resulting in a "rain" of fist sized chunks of porous stone as it falls back to the planet. Given the nature of the geology of Raisa, mining the planet would consist mainly of scooping up the dust of the vast deserts and processing it for extraction, but few have considered such an endeavor worthwhile.
