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". However, in the 1990s, it became known that Uranus and Neptune are really a distinct class of giant planets, being composed mainly of heavier ...
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 and expanded on in Theoretical Spectra and Atmospheres of Extrasolar Giant Planets, published before any successful direct or indirect observation of an extrasolar ...
In science fiction and fantasy, floating cities and islands are a common trope, ranging from cities and islands that float on water to ones that float in the atmosphere of a planet by purported scientific technologies or by magical means. While very large floating structures have been constructed or proposed in real life, aerial cities and ...

Mini-Neptune. A Mini-Neptune (sometimes known as a gas dwarf or transitional planet) is a planet less massive than Neptune but resembling Neptune in that it has a thick hydrogen - helium atmosphere, probably with deep layers of ice, rock or liquid oceans (made of water, ammonia, a mixture of both, or heavier volatiles).

An ice giant is a giant planet composed mainly of elements heavier than hydrogen and helium, such as oxygen, carbon, nitrogen, and sulfur. There are two ice giants in the Solar System: Uranus and Neptune . In astrophysics and planetary science the term "ice" refers to volatile chemical compounds with freezing points above about 100 K, such as ...
Shellworld. A shellworld is any of several types of hypothetical megastructures : A planet or a planetoid turned into series of concentric matryoshka doll -like layers supported by massive pillars. [1] A shellworld of this type features prominently in Iain M. Banks' novel Matter. A megastructure consisting of multiple layers of shells suspended ...
