1. Gas giant

   A gas giant is a giant planet composed mainly of hydrogen and helium. Gas giants are also called failed stars because they contain the same basic elements as a star. Jupiter and Saturn are the gas giants of the Solar System. The term "gas giant" was originally synonymous with "giant planet". However, in the 1990s, it became known that Uranus and Neptune are really a distinct class of giant planets, being composed mainly of heavier volatile substances (which are referred to as "ices"). For this reason, Uranus and Neptune are now often classified in the separate category of ice giants.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 consist of an outer layer of compressed molecular hydrogen surrounding a layer of liquid metallic hydrogen, with probably a molten rocky core inside. The outermost portion of their hydrogen atmosphere contains many layers of visible clouds that are mostly composed of water and ammonia. The layer of metallic hydrogen located in the mid-interior makes up the bulk of every gas giant and is referred to as "metallic" because the very large atmospheric pressure turns hydrogen into an electrical conductor. The gas giants' cores are thought to consist of heavier elements at such high temperatures (20,000 K [19,700 °C; 35,500 °F]) and pressures that their properties are not yet completely understood.The defining differences between a very low-mass brown dwarf (which can have a mass as low as roughly 13 times that of Jupiter) and a gas giant are debated. One school of thought is based on formation; the other, on the physics of the interior. Part of the debate concerns whether brown dwarfs must, by definition, have experienced nuclear fusion at some point in their history.

1. gas giant

   A gas giant is a large planet that is primarily composed of hydrogen, helium and other gases, as opposed to rock or other solid matter. The most recognized examples of gas giants in our solar system are Jupiter and Saturn. These planets are characterized by their massive sizes, multiple moons, ring systems, and low densities compared to terrestrial or rocky planets.

1. Gas giant

   A gas giant is a large planet that is not primarily composed of rock or other solid matter. There are four gas giants in the Solar System: Jupiter, Saturn, Uranus and Neptune. However, astronomers sometimes categorize Uranus and Neptune as "ice giants", in order to emphasize the differences in composition between them and larger gas giants like Jupiter and Saturn. Many extrasolar gas giants have been identified orbiting other stars. Planets above 10 Earth masses are termed giant planets. Lower-mass gassy planets are sometimes called "gas dwarfs". Objects large enough to start deuterium fusion are called brown dwarfs and these occupy the mass range between that of large gas giants and the lowest-mass stars. The 13 Jupiter mass cutoff is a rule of thumb rather than something of precise physical significance. Larger objects will burn most of their deuterium and smaller ones will burn only a little, and the 13 MJ value is somewhere in between. The amount of deuterium burnt depends not only on mass but also on the composition of the planet, especially on the amount of helium and deuterium present. The Extrasolar Planets Encyclopaedia includes objects up to 25 Jupiter masses, and the Exoplanet Data Explorer up to 24 Jupiter masses.

Examples of gas giant in a Sentence

1. Scott Bolton:

   Since its first orbit in 2016, Juno has delivered one revelation after another about the inner workings of this massive gas giant.

2. Shubham Kanodia:

   TOI-5205b’s existence stretches what we know about the disks in which these planets are born, in the beginning, if there isn’t enough rocky material in the disk to form the initial core, then one cannot form a gas giant planet. And at the end, if the disk evaporates away before the massive core is formed, then one cannot form a gas giant planet. And yet TOI-5205b formed despite these guardrails. Based on our nominal current understanding of planet formation, TOI-5205b should not exist; it is a ‘forbidden’ planet.

3. Jim Fuller:

   This is the first time we've been able to seismically probe the structure of a gas giant planet, and the results were pretty surprising.
