Raisa. A name that sounds hotter than the hottest sun. Hotter than a jedi's lightsaber. Hotter even than the queen of Hapes herself.
There is no way to escape heat in Raisa. First of all, the star-to-planet distance is very short. There is no atmosphere to block the solar beams. no ozone layer. Nothing. So is this small piece of hell so hot.
But the worse thing is the all-out volcanic activity. Huge range of volcanoes do divide the surface in 5 flat plains. Each range is thousands of klicks wide. And most volcanoes are active. Magma is vomited from the planet in many locations. But no gases, as none is included in the planet's chemical composition.
The plains are made of darkyellow/grey dust. Such a dust is the product of the most violent eruptions of Raisa. Rains of boiling dust are always quick, as no atmosphere does sustain it. But such rains are ravaging nearly everything on their way. Many volcanoes have been leveled by such "rains".
Some metals have been detected under the dusty plains of Raisa. No one is related having even dreamed of exploiting it. But who knows?
