A gas giant is a giant planet composed mainly of hydrogen and helium. [1] Jupiter and Saturn are the gas giants of the Solar System . The term "gas giant" was originally synonymous with " giant planet ".
Sudarsky's classification of gas giants for the purpose of predicting their appearance based on their temperature was outlined by David Sudarsky and colleagues in the paper Albedo and Reflection Spectra of Extrasolar Giant Planets [1] and expanded on in Theoretical Spectra and Atmospheres of Extrasolar Giant Planets, [2] published before any successful direct or indirect observation of an ...
Giant planets are sometimes known as gas giants, but many astronomers now apply the term only to Jupiter and Saturn, classifying Uranus and Neptune, which have different compositions, as ice giants. Both names are potentially misleading; the Solar System's giant planets all consist primarily of fluids above their critical points, where distinct gas
Astronomers have identified a planet that’s bigger than Jupiter yet surprisingly as fluffy and light as cotton candy. The gas giants in our solar system — Jupiter, Saturn, Uranus and Neptune ...
Jupiter is the fifth planet from the Sun and the largest in the Solar System.It is a gas giant with a mass more than 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun.
Located in the Kepler-90 System with eight known exoplanets, whose architecture is similar to that of the Solar System, with rocky planets being closer to Kepler-90 and gas giants being more distant. This largest, most massive and outermost planet orbits every ~331.6 days at a separation of 1.01 AU which is within the habitable zone of Kepler ...
Saturn is the sixth planet from the Sun and the second largest in the Solar System, after Jupiter. It is a gas giant, with an average radius of about nine times that of Earth. [27] [28] It has an eighth the average density of Earth, but is over 95 times more massive.
A planet in the Solar System beyond the asteroid belt, and hence refers to the gas giants. Pulsar planet: A planet that orbits a pulsar or a rapidly rotating neutron star. Rogue planet: Also known as an interstellar planet. A planetary-mass object that orbits the galaxy directly. Superior planets: Planets whose orbits lie outside the orbit of ...
