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.
Flybys of Jupiter’s moon Io, the only known volcanic world in our solar system, have captured images of a massive lava lake and a towering Matterhorn-like mountain.
A schema of Jupiter's ring system showing the four main components. For simplicity, Metis and Adrastea are depicted as sharing their orbit. (In reality, Metis is very slightly closer to Jupiter.) The planet Jupiter has a system of faint planetary rings. The Jovian rings were the third ring system to be discovered in the Solar System, after ...
Jupiter's Great Red Spot (GRS) is an elliptical shaped anticyclone, occurring at 22 degrees below the equator, in Jupiter's southern hemisphere. [38] The largest anticyclonic storm (~16,000 km) in our solar system, little is known about its internal depth and structure. [39]
Voyager 1 studied the weather, magnetic fields, and rings of the two gas giants and was the first probe to provide detailed images of their moons. As part of the Voyager program and like its sister craft Voyager 2 , the spacecraft's extended mission is to locate and study the regions and boundaries of the outer heliosphere and to begin ...
Jupiter's swirling clouds, in a true-color image taken by the Hubble Space Telescope in April 2017 [1] The atmosphere of Jupiter is the largest planetary atmosphere in the Solar System. It is mostly made of molecular hydrogen and helium in roughly solar proportions; other chemical compounds are present only in small amounts and include methane ...
Jupiter's North Pole. Jupiter's North Pole is the northernmost point of Jupiter. Like Jupiter's South Pole, it has a bluer surface color than the rest of Jupiter. It was first imaged in July 2016 with the Juno probe entering the polar orbit of Jupiter. At the same time, its polar cyclone was discovered, measuring just over 3,000 km, surrounded ...
The exploration of Jupiter has been conducted via close observations by automated spacecraft. It began with the arrival of Pioneer 10 into the Jovian system in 1973, and, as of 2023, has continued with eight further spacecraft missions in the vicinity of Jupiter. All of these missions were undertaken by the National Aeronautics and Space ...
