Origins & Early Life

A gas giant is a giant planet composed mainly of hydrogen and helium. There are two gas giants in the Solar System: Jupiter and Saturn. The term "gas giant" was originally synonymous with "giant planet".

Career & Major Achievements

However, starting in the 1970s and continuing into the 1980s, it became increasingly common to classify Uranus and Neptune separately as ice giants, a distinct class of giant planets composed mainly of heavier volatile substances (referred to as "ices"). Jupiter and Saturn consist mostly of hydrogen and helium, with heavier elements making up between 3 and 13 percent of their mass. They are thought to have a deep atmosphere of molecular hydrogen, with lower layers being more compressed, surrounding a layer of liquid metallic hydrogen, and with a molten rocky core inside.

Enduring Legacy & Impact

The outermost portions of their hydrogen atmospheres contain many layers of visible clouds that are mostly composed of water and ammonia. The layer of metallic hydrogen located in the mid-interior would make up the bulk of the mass of every gas giant, and it is referred to as "metallic" because under the immense weight of the atmosphere, the very high pressure turns hydrogen into an electrical conductor.

Historical Fact-Check Quiz: Gas giant

True or False: “It is a misconception that all gas giants are composed solely of hydrogen and helium, with no heavier elements present.”

Answer (FALSE ❌): Gas giants, such as Jupiter and Saturn, do contain heavier elements, which make up a measurable percentage of their total mass, alongside hydrogen and helium.
