Mercury albedo
Web2 apr. 2024 · Descriptions of alchemical processes often describe the reactions of sulfur and mercury. The Red King is sulfur -- the active, volatile and fiery principle -- while the White Queen is mercury -- the material, passive, fixed principle. Mercury has substance, but it has no definitive form on its own. It needs an active principle to shape it. WebThe first step in the computation of spherical albedo is determination of the geometric albedo. Observations of Mercury made at smaller phase angles are preferred for this …
