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 ...
Endor (designated: IX3244-A) is a fictional Planet in the Star Wars universe, known for its endless forests, savannahs, grasslands, mountain ranges, and a few oceans. The moon was the site of a pivotal battle depicted in Return of the Jedi. It is the homeworld of the sentient Dulok, Ewok, and Yuzzum species, as well as the semi-sentient Gorax ...
A Super-Earth is a type of exoplanet with a mass higher than Earth 's, but substantially below those of the Solar System's ice giants, Uranus and Neptune, which are 14.5 and 17 times Earth's, respectively. [1] The term "super-Earth" refers only to the mass of the planet, and so does not imply anything about the surface conditions or habitability.
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 ...
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 of proximity to a star.
Giant planet: A massive planet. They are most commonly composed primarily of 'gas' (hydrogen and helium) or 'ices' (volatiles such as water, methane, and ammonia), but may also be composed primarily of rock, which would make one a Mega Earth. Regardless of their bulk compositions, giant planets normally have thick atmospheres of hydrogen and ...
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.
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 ...
