is jupiter a gas giant

and leave you all dangling in the mid firmament. Compositionally, the two worlds are totally different. Jupiter’s diameter is 11 times Earth’s diameter, making it 1331 times larger than Earth in volume. [48], A 1997 survey of early astronomical records and drawings suggested that a certain dark surface feature discovered by astronomer Giovanni Cassini in 1690 may have been an impact scar. It might even have been observed in the 1600s. [77] This field is thought to be generated by eddy currents—swirling movements of conducting materials—within the liquid metallic hydrogen core. Jupiter is the biggest planet in our solar system. London. The extreme pressures and temperatures deep inside the planet crush, melt and vaporize spacecraft trying to fly into the planet. Gas giants are also called “Jovian planets,” named after Jupiter To be considered a gas giant, the planet has to be made up of mostly gas, be located in the outer area of the solar system, and have a mass that is ten times that of Earth. Sometimes it looks more red or brown, showing the new material it spins around. Furthermore, the famous red spot has been visible from Earth for hundreds of years and has been identified as a gigantic swirling storm, and you can even see it for yourself. As a result, radio waves are generated through a cyclotron maser mechanism, and the energy is transmitted out along a cone-shaped surface. The merged feature was named Oval BA, and has been nicknamed Red Spot Junior. But by definition, if a gas giant is massive enough to ‘ignite’ deuterium fusion it is not a gas giant at all, but a brown dwarf. Jupiter’s density under standard pressure and temperature would be 13,000 times lower than its average actual density. "Hang me a golden chain from heaven, and [152], The eccentricity of their orbits causes regular flexing of the three moons' shapes, with Jupiter's gravity stretching them out as they approach it and allowing them to spring back to more spherical shapes as they swing away. [141] When Juno reaches the end of the mission, it will perform a controlled deorbit and disintegrate into Jupiter's atmosphere. Jupiter is primarily composed of hydrogen with a quarter of its mass being helium, though only about a tenth of the number of molecules are helium. The gas is ionized in the magnetosphere, producing sulfur and oxygen ions. Material that would normally fall back to the moon is pulled into Jupiter because of its strong gravitational influence. As a result, Jupiter is thought to have about as large a diameter as a planet of its composition and evolutionary history can achieve. A dispersed and only vaguely distinct retrograde group that covers all the outermost moons. The Kirkwood gaps in the asteroid belt are mostly caused by Jupiter, and the planet may have been responsible for the Late Heavy Bombardment of the inner Solar System's history.[166]. [35], Jupiter's upper atmosphere is about 90% hydrogen and 10% helium by percent volume of gas molecules. A torus of ionized atoms was discovered along Io's orbital path, and volcanoes were found on the moon's surface, some in the process of erupting. Scientists discovered that there are three forms of radio signals transmitted from Jupiter. Because of its rapid rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator). [164] In a similar way, the moons Thebe and Amalthea probably produce the two distinct components of the dusty gossamer ring. Jupiter is the fifth planet from the Sun and the largest planet within the Solar System. The pharmacist Heinrich Schwabe produced the earliest known drawing to show details of the Great Red Spot in 1831. [43], The cloud layer is only about 50 km (31 mi) deep, and consists of at least two decks of clouds: a thick lower deck and a thin clearer region. As a gas giant, Jupiter doesn’t have a true surface. [186] The Chinese, Vietnamese, Koreans and Japanese called it the "wood star" (Chinese: 木星; pinyin: mùxīng), based on the Chinese Five Elements. A tightly clustered group of moons with orbits around 11,000,000–12,000,000 km from Jupiter. bind the chain about some pinnacle of Olympus EJSM/Laplace would have consisted of the NASA-led Jupiter Europa Orbiter and the ESA-led Jupiter Ganymede Orbiter. Yes. Another similarity with the Sun is that Jupiter lacks a solid surface, too. [27] Regularly these systems include a few planets with masses several times greater than Earth's (super-Earths), orbiting closer to their star than Mercury is to the Sun, and sometimes also Jupiter-mass gas giants close to their star. Scientists believe the Spot is a giant vortex similar to the Great Red Spot, and also appears to be quasi-stable like the vortices in Earth's thermosphere. If true, this would predate Galileo's discovery by nearly two millennia. [135], The first spacecraft to orbit Jupiter was the Galileo probe, which entered orbit on December 7, 1995. Scientists consider a surface level for comparison, where pressure equals one bar, like the atmospheric pressure on Earth. The name gas giant was coined in 1952 by science fiction writer James Blish to refer to all the giant planets. It may also have a rocky core of heavier elements,[21] but like the other giant planets, Jupiter lacks a well-defined solid surface.
