Jupiter and Saturn
Jupiter and Saturn consist mostly of hydrogen and helium, with heavier elements making up between 3 and 13 percent of the mass. Their structures are thought to consist of an outer layer of molecular hydrogen, surrounding a layer of liquid metallic hydrogen, with a probable molten core with a rocky composition. The outermost portion of the hydrogen atmosphere is characterized by many layers of visible clouds that are mostly composed of water and ammonia. The metallic hydrogen layer makes up the bulk of each planet, and is described as "metallic" because the great pressure turns hydrogen into an electrical conductor. The core is thought to consist of heavier elements at such high temperatures (20,000 K) and pressures that their properties are poorly understood.

Famous quotes containing the words jupiter and/or saturn:
“Few and signally blessed are those whom Jupiter has destined to be cabbage-planters. For they’ve always one foot on the ground and the other not far from it. Anyone is welcome to argue about felicity and supreme happiness. But the man who plants cabbages I now positively declare to be the happiest of mortals.”
—François Rabelais (c. 1494–1553)
“From you have I been absent in the spring,
When proud pied April, dressed in all his trim,
Hath put a spirit of youth in every thing,
That heavy Saturn laughed and leaped with him.”
—William Shakespeare (1564–1616)
