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 ...
List of planet types. From top to bottom: Mercury, Venus without its atmosphere, Earth and the Moon, Mars, Jupiter, Saturn, Uranus, and Neptune in false colour (not to scale) The following is a list of planet types by their mass, orbit, physical and chemical composition, or by another classification. The IAU defines that a planet in the Solar ...
Updated May 14, 2024 at 7:50 PM. CAPE CANAVERAL, Fla. (AP) — Astronomers have identified a planet that’s bigger than Jupiter yet surprisingly as fluffy and light as cotton candy. The exoplanet ...
The special chemicals in the warhead reacted in the planet's core, destabilizing the planet. Mass Shadow Generator (EU): Used the gravity of a planet to create a quantum singularity, de-stabilizing the planet. Eclipse-class dreadnought (EU): A Super Star Destroyer armed with a less-powerful version of the Death Star superlaser.
Tyche (hypothetical planet) Tyche / ˈtaɪki / was a hypothetical gas giant located in the Solar System 's Oort cloud, first proposed in 1999 by astrophysicists John Matese, Patrick Whitman and Daniel Whitmire of the University of Louisiana at Lafayette. [1] [2] They argued that evidence of Tyche's existence could be seen in a supposed bias in ...
Jupiter is the fifth planet from the Sun and the largest in the Solar System.A gas giant, Jupiter's mass is more than two and a half times that of all the other planets in the Solar System combined and slightly less than one one-thousandth the mass of the Sun. Jupiter orbits the Sun at a distance of 5.20 AU (778.5 Gm) with an orbital period of 11.86 years.
Class I: Ammonia clouds. Jupiter and Saturn, two Sudarsky class I gas giants. Gaseous giants in this class have appearances dominated by ammonia clouds. These planets are found in the outer regions of a planetary system. They exist at temperatures less than about 150 K (−120 °C; −190 °F).
Artist's conception of HD 209458 b transiting its star. Chthonian planets ( / ˈkθoʊniən /, sometimes 'cthonian') are a hypothetical class of celestial objects resulting from the stripping away of a gas giant 's hydrogen and helium atmosphere and outer layers, which is called hydrodynamic escape. Such atmospheric stripping is a likely result ...
