The four giant planets of the Solar System: ( top) Jupiter and Saturn ( gas giants) ( bottom) Uranus and Neptune ( ice giants) Shown in order from the Sun and in true color. Sizes are not to scale. A giant planet, sometimes referred to as a jovian planet ( Jove being another name for the Roman god Jupiter ), is a diverse type of planet much ...
The "ice giant" (sometimes known as "water giant") planets Uranus and Neptune are thought to have a supercritical water ocean beneath their clouds, which accounts for about two-thirds of their total mass, most likely surrounding small rocky cores, although a 2006 study by Wiktorowicz and Ingersall ruled out the possibility of such a water ...
A rogue planet (Likely a sub-brown dwarf) that is surrounded by a protoplanetary disk. It is one of youngest free-floating substellar objects with 0.5–10 Myr. GSC 06214-00210 b: 1.8 ± 0.5: 16 M J, likely brown dwarf TrES-4b: 1.799 ± 0.063: This planet has a density of 0.2 g/cm 3, about that of balsa wood, less than Jupiter's 1.3g/cm 3. WASP ...
Manus Plate – Tiny tectonic plate northeast of New Guinea. North Bismarck Plate – Small tectonic plate in the Bismarck Sea north of New Guinea. North Galápagos Microplate – Tectonic plate off west South America. Solomon Sea Plate – Minor tectonic plate near the Solomon Islands archipelago in the Pacific Ocean.
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.
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 ...
Uranus is the seventh planet from the Sun. It is a gaseous cyan -coloured ice giant. Most of the planet is made of water, ammonia, and methane in a supercritical phase of matter, astronomy calls "ice" or volatiles. The planet's atmosphere has a complex layered cloud structure and has the lowest minimum temperature of 49 K (−224 °C; −371 ...
Planetary oceanography, also called astro-oceanography or exo-oceanography, [1] is the study of oceans on planets and moons other than Earth. Unlike other planetary sciences like astrobiology, astrochemistry, and planetary geology, it only began after the discovery of underground oceans in Saturn's moon Titan [2] and Jupiter's moon Europa.
