The Moons of Jupiter

Erinome. Erinome. Erinome was discovered on Nov. 23, , by Scott S. Sheppard, David C. Jewitt, Yanga R. Fernandez and Eugene Magnier at the Mauna Kea Observatory in Hawaii. This tiny moon of Jupiter was first spotted in The discovery announcement was made in July Why is Jupiter moon named Io? Io was the first of Jupiter’s moons discovered by Galileo Galilei on Jan. 8, Galileo’s discovery eventually led to the understanding that planets orbit the sun, instead of our solar system revolving around Earth. Galileo first referred to this moon as Jupiter I. In the mids, the moon was renamed elvalladolid.comted Reading Time: 6 mins.

Jupiter has 79 known moons, the largest ,oon of moons for a planet in the solar system, that vary in size and characteristics. Dalled have grouped the moons into two broad categories namely regular satellites and irregular satellites.

The regular satellites have almost circular orbits and are prograde while irregular satellites are smaller with eccentric orbits. There are two sub-groups of regular aclled — inner satellites and main satellites.

NASA observes that main group Galilean Moons consists of some of the largest bodies in the solar system besides the sun and planets. On the other hand, there are two sub-groups of irregular satellites namely prograde and retrograde. This article analyses some of the well-researched moons orbiting around Jupiter. Amalthea is the number three moon by distance from the planet and the largest of the inner satellites.

Observers believe that this moon consists of porous water ice below the large craters and ridges making up its surface. Discovered inthis planet orbits Jupiter at a distance of 2.

Photographs show Amalthea to be red in color in what may be sulfur originating from the nearby jupoter, Io. Observations also show that the leading hemisphere appears to be 1.

This radiation may be due to the influence of the Jovian heat flux, sunlight reflected from Jupiter, and bombardment of charged particles. Callisto is the second-largest moon of Jupiter and third-largest moon in the Mmoon system. This Galilean moon claled a diameter of 2, miles and an orbital radius of about 1, miles. Callisto is tidally locked during rotation meaning that it orbits Jupiter with the same hemisphere facing inwards making Jupiter seemingly stands still in Callisto's sky.

This planet has th equal rock and ice composition with confirmed compounds like water ice, carbon dioxide, silicates, and organic compounds. Investigations also reveal a possible underground ocean of liquid water and surface features like ring structures and craters of different shapes.

Other characteristics include a thin atmosphere of carbon dioxide and low radiation levels leaving speculations of possibilities how to turn off audio description on tv the moon can support some form how much does it cost to make a website uk life.

Evidence shows that Callisto orbits at a distance of approximately 1, miles and has an orbital period of Whaf eccentricity is between 0. Io is the innermost Galilean moon with the highest density of all the moons and over active volcanoes producing sulfur and sulfur dioxide resulting from tidal heating from within its interior. There are over mountains, some taller than Mount Everest. Critical analysis reveals that the volcanic plumes and lava flows are responsible for the surface color of different shades of yellow, red, white, black, and green or, as people call it rotten orange or pizza colors.

Atmospheric studies indicate that Io has a thin atmosphere consisting of sulfur dioxide, sulfur monoxide, sodium chloride, and atomic sulfur and oxygen.

Made up of silicate rocks and iron, Io teh a radius of 1, With a slight ellipsoid in shape, this moon has an orbital eccentricity of 0. Galileo Galilei and Simon Marius hold the credits for being the first people to sport the four Galilean moons in with up to 69 moons discovered to date. Highly inclined satellites prograde irregulars have names ending with "a" or "o" whereas callee ending with "e" belong to retrograde irregulars.

Examples of Some of the Moons of Jupiter

Overview Jupiter has 53 named moons. Others are awaiting official names. Combined, scientists now think Jupiter has 79 moons. There are many interesting moons orbiting the planet, but the ones of most scientific interest are the first four moons discovered beyond Earth—the Galilean satellites. The images were taken 5 days prior to arrival and end when the spacecraft was 3 million miles distant.

The innermost moon is volcanic Io; next in line is the ice-crusted ocean world Europa, followed by massive Ganymede, and finally, heavily cratered Callisto. The Galilean Moons. The planet Jupiter's four largest moons are called the Galilean satellites after Italian astronomer Galileo Galilei, who first observed them in The German astronomer Simon Marius claimed to have seen the moons around the same time, but he did not publish his observations and so Galileo is given the credit for their discovery.

These large moons, named Io, Europa, Ganymede, and Callisto, are each distinctive worlds. Io is the most volcanically active body in the solar system. Io's surface is covered by sulfur in different colorful forms. As Io travels in its slightly elliptical orbit, Jupiter's immense gravity causes "tides" in the solid surface that rise feet meters high on Io, generating enough heat for volcanic activity and to drive off any water.

Io's volcanoes are driven by hot silicate magma. Europa's surface is mostly water ice, and there is evidence that it may be covering an ocean of water or slushy ice beneath. Europa is thought to have twice as much water as does Earth. This moon intrigues astrobiologists because of its potential for having a "habitable zone. Ganymede is the largest moon in the solar system larger than the planet Mercury , and is the only moon known to have its own internally generated magnetic field.

Callisto's surface is extremely heavily cratered and ancient—a visible record of events from the early history of the solar system.

However, the very few small craters on Callisto indicate a small degree of current surface activity. The interiors of Io, Europa and Ganymede have a layered structure as does Earth. Io has a core, and a mantle of at least partially molten rock, topped by a crust of solid rock coated with sulfur compounds. Europa and Ganymede both have a core; a rock envelope around the core; a thick, soft ice layer; and a thin crust of impure water ice.

In the case of Europa, a global subsurface water layer probably lies just below the icy crust. Layering at Callisto is less well defined and appears to be mainly a mixture of ice and rock. Three of the moons influence each other in an interesting way. Io is in a tug-of-war with Ganymede and Europa, and Europa's orbital period time to go around Jupiter once is twice Io's period, and Ganymede's period is twice that of Europa.

In other words, every time Ganymede goes around Jupiter once, Europa makes two orbits and Io makes four orbits. The moons all keep the same face towards Jupiter as they orbit, meaning that each moon turns once on its axis for every orbit around Jupiter.

Pioneers 10 and 11 to and Voyager 1 and Voyager 2 offered striking color views and global perspectives from their flybys of the Jupiter system. From to , the Galileo spacecraft made observations from repeated elliptical orbits around Jupiter, passing as low as miles kilometers over the surfaces of the Galilean moons.

These close approaches resulted in images with unprecedented detail of selected portions of the surfaces. Close-up images taken by the Galileo spacecraft of portions of Europa's surface show places where ice has broken up and moved apart, and where liquid may have come from below and frozen smoothly on the surface. The low number of craters on Europa leads scientists to believe that a subsurface ocean has been present in recent geologic history and may still exist today.

The heat needed to melt the ice in a place so far from the Sun is thought to come from inside Europa, resulting primarily from the same type of tidal forces that drive Io's volcanoes. Clipper will conduct detailed reconnaissance of Jupiter's moon Europa to see whether the icy moon could harbor conditions suitable for life. Jupiter Moons. A technique for scanning Mars rocks for microscopic fossils is also being developed to hunt for microbes on Enceladus, Titan, and Europa.

The spacecraft will use multiple flybys of the moon to investigate the habitability of this ocean world. Jupiter's Visible and Invisible Winds. The gas-giant orbiter is illuminating the provenance of Jovian polar light shows. Zodiacal light is sunlight reflected toward Earth by dust orbiting the Sun. Juno scientists now think Mars may be the source of the dust. A wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way.

JPL's lucky peanuts are an unofficial tradition at big mission events. Deep Jet Streams in Jupiter's Atmosphere. Phobos orbits through a stream of charged atoms and molecules that flow off the atmosphere of Mars, new research shows. A Hot Spot on Jupiter. The spacecraft will become an explorer of the full Jovian system — Jupiter and its rings and moons. Saturn and Jupiter's Great Conjunction. Skywatchers are in for a treat soon as Jupiter and Saturn appear to merge into what's become popularly known as the "Christmas Star.

The Great Conjunction of Jupiter and Saturn. Some of Juno's latest findings touch on "hot spots" in the planet's atmosphere. Tips for photographing the sky during December's conjunction of Saturn and Jupiter.

How to Photograph the Conjunction of Saturn and Jupiter. Plumes of water vapor that may be venting into space from Jupiter's moon Europa could come from within the icy crust itself, according to new research. New experiments re-create the environment of Europa and find that the icy moon shines, even on its nightside.

The effect is more than just a cool visual.
