Nitrogen Ice

Explanation: Solid nitrogen at -212 degrees C. With surface temperatures around 44 K (-229 degrees C) or so, the surface of Pluto is cold enough that nitrogen, with a melting point of 63.15 K (-210 degrees C, or -346 degrees F) and the major component of Earth's gaseous atmosphere, can exist as solid ice.
