Asteroidal water trap water between them; the large surface area created can hold much water. Minerals which appear waterless to the eye or hand may nevertheless be hydrated. Most "rocks" are silicates, or in some cases metal oxides, containing an oxygen fraction. Hydrogen content, as substitutions or interstitials, can react with oxygen (displacing its existing cation) to form hydroxide or water. The solar wind is a reducing environment, containing hydrogen atoms and protons (effectively hydrogen, in the form of hydrogen nuclei). Either may be implanted into exposed surfaces, as the small hydrogen atom is highly soluble. A lesser contribution may come from
