Here is a list of 57 officially named moonsof Jupiter along with details on their discovery, according to NASA. Adrastea: Discovered in July 1979 by the Voyager science team. Aitne: Discovered on 9 December 2001 by Scott S. Sheppard, David C. Jewitt and Jan T. Kleyna during observations at the Mauna Kea Observatory, Hawaii. Amalthea: Discovered on ...
Diameter: 3,270 miles (5,260 kilometers) Jupiter's moon Ganymede is the biggest moon in the solar system, it is even larger than the planet Mercury. It is also the only moon that we know of to have its own magnetic field, which causes impressive polar light shows — auroras. Furthermore, the giant moon could harbor a subsurface saltwater ocean which...
Diameter: 1,940 miles (3,100 km) Europa is thought to have an iron core, rocky mantle and a surface of frozen water ice that sits atop a vast saltwater ocean. According to NASA, the icy moon Europa is thought to be the most promising place to find an environment that could support life forms beyond Earth. The theorized subsurface saltwater ocean co...
Diameter: 2,260 miles (3,640 km) The most volcanically active place in the solar system, Io is a remarkable world locked in a "tug-of-war" between Jupiter's gravity and pulls from neighboring Galilean moons Europa and Ganymede. The turbid environment continually renews itself, smoothing out craters with vast lakes of lava spewed from one of the hun...
Diameter: 2,995 miles (4,820 km) Jupiter's second-largest moon Callisto is the third-largest moon in the solar system. The moon's surface is thought to be about 4 billion years old, making it the oldest icy surface in the solar system. After being pummeled for4 billion years by impactors such as meteors, it comes as no surprise that Callisto also h...
The Jovian system is no stranger to guests. Since its first visitor in December 1973 when NASA's Pioneer 10 spacecraft conducted a flyby of the gas giant, Jupiter has attracted numerous flybys and close encounters from trailblazing probes. Pioneer 11 made a close approach a year after Pioneer 10 in December 1974 and Voyager 1 and Voyager 2flew past...
With the right equipment, it is possible to spot Jupiter and its four Galilean moons. Our visible planets guidetells you where you can find the brightest planets that month and the best times to view them. Jupiter can reach magnitude -2.94 at this brightness you can spot the gas giant with the naked eye, a pair of binoculars or a small telescope. (...
