The Frigid Nitrogen Glaciers and Icy Highlands of 2015 RR245
Deep within the trans-Neptunian expanse , far beyond the reach of the major giants, lies a diminutive, solitary wanderer designated 2015 RR245 . This object serves as a pristine relic of the early solar system’s construction, a dwarf planet characterized by its immense, highly elongated orbital path that carries it from the depths of the outer Kuiper Belt into the cold darkness of the scattered disk . Its existence provides a vital window into the collisional and thermal history of the outer debris populations that have remained largely undisturbed for billions of years. Geological Composition and Surface Texture The surface of 2015 RR245 is a testament to the preservation of volatile ices . Spectroscopic analysis suggests a mantle dominated by nitrogen, methane, and carbon monoxide ices. Unlike bodies closer to the Sun, this dwarf planet lacks the thermal energy required to drive significant internal differentiation or active resurfacing. Instead, its crust exhibits...
