It is also likely due to the presence of a layer of ammonia ice crystals in the planets upper atmosphere. In contrast, the gas giant atmospheres are composed mostly of hydrogen and helium. Mercury is the innermost planet of the solar system, orbiting the sun at an average distance of 58-million kilometres. c. they are composed of heavy materials like rock and water. But these tiny particles that float about and settle on surfaces play an important role across the solar system. Is the Ozone Layer Finally Healing Itself?
