Pluto
No. While frozen methane, carbon dioxide, and nitrogen do exist on Pluto, they are not metals.
No, snow does not contain nitrogen. Snow is made up of frozen water vapor and does not typically contain nitrogen.
Nitrogen can freeze anything and i think it is a frozen gas.
The ice covering Pluto is primarily made of frozen methane and nitrogen, giving it a bluish tint, while the ice covering Charon is mostly composed of water ice. Additionally, the surface of Pluto undergoes seasonal changes due to its elliptical orbit, while Charon's surface remains more stable.
No. Pluto's surface is made mostly of frozen nitrogen.
3 million years
