Jupiter's helium abundance is 80% of the Sun's, similar to Saturn's composition. The ongoing contraction of Jupiter's interior generates more heat than the planet receives from the Sun. Its internal structure is believed to consist of an outer mantle of fluid metallic hydrogen and a diffuse inner core of denser material.
A polar stereographic projection of Jupiter's atmosphere centered about Jupiter's south pole. The visible surface of Jupiter is divided into several bands parallel to the equator. There are two types of bands: lightly colored zones and relatively dark belts. [5] The wider Equatorial Zone (EZ) extends between latitudes of approximately 7°S to 7 ...
Jupiter's Great Red Spot (GRS) is an elliptical shaped anticyclone, occurring at 22 degrees below the equator, in Jupiter's southern hemisphere. [39] The largest anticyclonic storm (~16,000 km) in our solar system, little is known about its internal depth and structure. [40]
The Juno spacecraft has been orbiting Jupiter since 2016 and it has already provided us with a wealth of information about the gas giant. ... about Jupiter that give us a look at the planet's ...
Io (/ ˈ aɪ. oʊ /), or Jupiter I, is the innermost and second-smallest of the four Galilean moons of the planet Jupiter.Slightly larger than Earth's moon, Io is the fourth-largest moon in the Solar System, has the highest density of any moon, the strongest surface gravity of any moon, and the lowest amount of water by atomic ratio of any known astronomical object in the Solar System.
The magnetosphere of Jupiter is the cavity created in the solar wind by Jupiter's magnetic field.Extending up to seven million kilometers in the Sun's direction and almost to the orbit of Saturn in the opposite direction, Jupiter's magnetosphere is the largest and most powerful of any planetary magnetosphere in the Solar System, and by volume the largest known continuous structure in the Solar ...
Some models predict that there may have been several generations of Galilean satellites in Jupiter's early history. Each generation of moons to have formed would have spiraled into Jupiter and been destroyed, due to tidal interactions with Jupiter's proto-satellite disk, with new moons forming from the remaining debris. By the time the present ...
Amalthea is in a close orbit around Jupiter and is within the outer edge of the Amalthea Gossamer Ring, which is formed from dust ejected from its surface. [11] Jupiter would appear 46.5 degrees in diameter from its surface. [b] Amalthea is the largest of the inner satellites of Jupiter and is irregularly shaped and reddish in color. It is ...
