Rosha is a brutally cold planet, one of those with fairly uniform terrain throughout - frozen tundra and vast glaciers. However, coming from far above in space, the planet’s atmosphere reflects off a beautiful blue hue. While the color is mostly contributed to the way that the oxygen reflects off light coming from Leemurtoo, another contributor to the beautiful blue color is the water deep under the glaciers. A deep-sea expedition to Rosha reports that they were not able to reach the ocean floor of the ocean that sits under the thick translucent glacier layer. It leads to the conclusion that the solid core of the planet is actually quite small, though very dense, so to generate enough gravity to maintain the water and the atmosphere. Aside from the harsh cold weather, the atmosphere is actually quite pleasant for humans and humanoid species. The atmosphere content is similar to that of Coruscant, with a little bit less atmospheric pressure, so that some visitors find themselves breathe a little bit shallower and quicker.

Because of the climate, there are not large quantities of life forms on Rosha. A thickly furred pack animal named Sandusk is perhaps the most commonly encountered here on this planet. They are mild-mannered and most likely found digging deep under the snow to feed on the moss-like vegetation that can withstand living in the cold. There are not a lot of predatory creatures on this planet, probably because there are not a lot of animals to prey upon. The life forms found in the ocean under the thick glacier layers are probably more interesting. Most notably, a creatively nicknamed “lantern fish” is often the talk of the town when Rosha is being discussed among explorers and scientists. With two sets of skeletons, both interior and exterior, the lantern fish is a tough predator of the deep seas. To cope with the typically dark conditions under the thick glaciers, these lantern fish actually have a lantern-like organ extending from the top of their heads, with a biologically powered “light bulb” at the end of the extension. The light paves way for the lantern fish to see roughly two meters in front of it. Lantern fish are quite a distinctive species for any world.

Scientists are noticing a trend where the average temperature on Rosha is increasing by a fraction of a degree every fifty years for the past few centuries. Perhaps in as soon as a few thousand years, the climate of this planet will be completely different. The temperature change is most noticeable in the waters under the glacier layer, leading to the hypothesis that the temperature change is caused by rising core temperatures. If the trend continues, Rosha may shed its image as the harsh icy world. It is hard even for ecologists to predict how this planet will change if a thaw happens as most life forms’ body structures are built to fit in this cold environment; as evolution and natural selection are near impossible to predict, it is not a topic that has been theorized too much among experts.
