Jupiter : the largest of the planets and fifth in order from the sun — Webster

Oxford, OneLook, Free Dictionary, Wiktionary, Urban Dictionary

Encyclopedia

Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a giant planet with a mass one-thousandth that of the Sun, but two and a half times that of all the other planets in the Solar System combined. Jupiter is a gas giant, along with Saturn, with the other two giant planets, Uranus and Neptune, being ice giants. Jupiter was known to astronomers of ancient times. The Romans named it after their god Jupiter.

Jupiter is primarily composed of hydrogen with a quarter of its mass being helium, though helium comprises only about a tenth of the number of molecules. It may also have a rocky core of heavier elements, but like the other giant planets, Jupiter lacks a well-defined solid surface. 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). The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries. A prominent result is the Great Red Spot, a giant storm that is known to have existed since at least the 17th century when it was first seen by telescope. Surrounding Jupiter is a faint planetary ring system and a powerful magnetosphere. Jupiter has at least 67 moons, including the four large Galilean moons discovered by Galileo Galilei in 1610. Ganymede, the largest of these, has a diameter greater than that of the planet Mercury. — Wikipedia

NASA Investigates Invisible Magnetic Bubbles in Outer Solar System (NASA Goddard)
Juno shows Jupiter’s magnetic field is very different from Earth’s (Bob Yirka, Phys.org)


In this animation the viewer is taken low over Jupiter’s north pole to illustrate the 3-D aspects of the region’s central cyclone and the eight cyclones that encircle it.

The movie utilizes imagery derived from data collected by the Jovian Infrared Auroral Mapper (JIRAM) instrument aboard NASA’s Juno mission during its fourth pass over the massive planet. Infrared cameras are used to sense the temperature of Jupiter’s atmosphere and provide insight into how the powerful cyclones at Jupiter’s poles work. In the animation, the yellow areas are warmer (or deeper into Jupiter’s atmosphere) and the dark areas are colder (or higher up in Jupiter’s atmosphere). In this picture the highest “brightness temperature” is around 260K (about -13°C) and the lowest around 190K (about -83°C). The “brightness temperature” is a measurement of the radiance, at 5 µm, traveling upward from the top of the atmosphere towards Juno, expressed in units of temperature.
