[Photos of Ganymede, Jupiter's Largest Moon]. [118], Another canceled proposal to orbit Ganymede was the Jupiter Icy Moons Orbiter. It would of course cause much higher tidal forces than the moon. The Galilean moons are the four largest moons of Jupiter: Io, Europa, Ganymede, and Callisto. Get breaking space news and the latest updates on rocket launches, skywatching events and more! How would it look in the sky, if it was at the same distance as the Moon? Earth's Moon vs. Ganymede - This animation puts Earth's moon next to Jupiters moon Ganymede, the largest in the solar system. [109][110], On December 25, 2019, the Juno spacecraft flew by Ganymede during its 24th orbit of Jupiter, and got images of the moon's polar regions.

he:גנימד This is pretty dense - about three times Earth's density. We do not know if Ganymede holds life under its thick icy exterior. Receive mail from us on behalf of our trusted partners or sponsors?

Scientists will try to figure out more about its ocean and icy crust, map its surface in detail, learn about the interior, probe the atmosphere and study the magnetic field. You can check out my social media profiles by clicking on their icons.

The discovery, along with three other Jovian moons , was the first time a moon was discovered orbiting a planet other than Earth.

NASA Scientists Discover ‘Weird' Molecule in Titan's Atmosphere New results from NASA's Juno mission suggest that either "sprites" or "elves" could be dancing in the upper atmosphere of Jupiter. el:Γανυμήδης (δορυφόρος)eo:Ganimedo (luno)

The grooves, which were likely formed as a result of tectonic activity or water being released from beneath the surface, are as high as 2,000 feet and stretch for thousands of miles. Typically found in planets, including Earth and Jupiter, a magnetosphere is a comet-shaped region in which charged particles are trapped or deflected. And if you have a news tip, correction or comment, let us know at: community@space.com. What if Ganymede was the Earth’s second moon? A 100kg man would weigh 14.6kg on Ganymede. Variations in the glow and the color of the glow itself could reveal information about the composition of ice on Europas su.

Jupiter's moon Ganymede is the largest satellite in the solar system. Galileo's discovery eventually led to the understanding that planets orbit the sun, instead of our solar system revolving around Earth. [120] Another old proposal was called The Grandeur of Ganymede. It has the highest mass of all planetary satellites with 2.01 times the mass of the Earth's moon. wuu:木卫三

The composite, which combines images taken with green, … Please deactivate your ad blocker in order to see our subscription offer. The field strength of the induced field at the magnetic equator is about 60 nT—half of that of the ambient Jovian field. The “rocking” seen by the auroras gives evidence that the probable ocean underneath is salty, more salty than oceans of Earth, scientists said at the time.

It has a mean radius of 2634.1±0.3 km (about 1636 miles, 0.413 Earths). Top 6 Biggest Prehistoric Crocodiles lit) pt:Ganímedes (satélite) [112] EJSM consisted of the NASA-led Jupiter Europa Orbiter, the ESA-led Jupiter Ganymede Orbiter, and possibly a JAXA-led Jupiter Magnetospheric Orbiter. For comparison with Earth, Miami, Florida lies at 26 degrees north latitude, and Berlin, Germany is located at 52 degrees north. id:Ganymede ur:گانیمید A global image mosaic of Jupiter's moon, Ganymede created with images from the Voyager and Galileo missions. [114] The spacecraft will orbit Ganymede and conduct multiple flyby investigations of Callisto and Europa. If the ratio is unity, then the resonance is the Laplace resonance. [98][99][100][101] In the latter case, modeling suggests that differentiation would become a runaway process at Ganymede but not Callisto.

sv:Ganymedes (måne) Jupiter and its moons receive less than 1/30th the amount of sunlight that the Earth does, and Ganymede has essentially no atmosphere to trap heat. [91], In addition to the intrinsic magnetic moment, Ganymede has an induced dipole magnetic field. The discovery of the four Galilean satellites eventually led to the understanding that planets in our solar system orbit the sun, instead of our solar system revolving around Earth. Largest Great White Sharks Ever Recorded Compared to Earth's polar caps, Ganymede's polar terrain is relatively vast. Compared to Earth's polar caps, Ganymede's polar terrain is relatively vast. This site uses Akismet to reduce spam. The surface number density and pressure were calculated from the column densities reported in Hall, et al. The discovery, along with three other Jovian moons, was the first time a moon was discovered orbiting a planet other than Earth. They refined its size, revealing it was larger than Saturn’s moon Titan, which was previously thought to have been bigger. Galileo called this moon Jupiter III. So it wouldn’t look like that photo for long, it would quickly turn into a blue and white swirly ball. m3,[23] which is three times larger than the magnetic moment of Mercury. nds:Ganymed (Maand)

In Depth. The images were taken at a range of 97,680 to 109,439 kilometers (60,696 to 68,002 mi). Planetary magnetic fields are fairly complex, so to make a good comparison, let’s model the magnetospheres of Earth and Ganymede as simple magnetic dipoles. Ganymede is the largest and most massive moon in the Solar System. Learn how your comment data is processed. Download high-resolution animations using links below.

Several probes flying by or orbiting Jupiter have explored Ganymede more closely, including four flybys in the 1970s, and multiple passes in the 1990s to 2000s.eval(ez_write_tag([[300,250],'ourplnt_com-banner-1','ezslot_3',198,'0','0'])); Pioneer 10 approached in 1973 and Pioneer 11 in 1974, and they returned information about the satellite.

Size: Ganymede's mean radius is 1,635 miles (2,631.2 km).

Zeus, a counterpart of Jupiter in Roman mythology, carried Ganymede, who had taken the form of an eagle, to Olympus, where he became a cupbearer to the Olympian gods and one of Zeus' lovers. Several probes flying by or orbiting Jupiter have explored Ganymede more closely, including four flybys in the 1970s, and multiple passes in the 1990s to 2000s. The induced moment is directed radially to or from Jupiter following the direction of the varying part of the planetary magnetic field.

North is to the top of the picture. Visit our corporate site. In 1995, the Galileo spacecraft entered orbit around Jupiter and between 1996 and 2000 made six close flybys to explore Ganymede. [37] These flybys are denoted G1, G2, G7, G8, G28 and G29. tt:Ганимед (иярчен) Future US, Inc. 11 West 42nd Street, 15th Floor, The grooved terrain was also seen. (Image credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute). The intrinsic field strength at the poles is two times that at the equator—1440 nT. The planet has an ocean that contains more water than Earth’s oceans, though at far greater pressures than even the bottom of the Mariana Trench in the Pacific Ocean. Finally, the camera flys through the Jovian system to show all four Galilean satellites orbting around Jupiter. Ganymede's magnetosphere is entirely embedded within the magnetosphere of Jupiter. The resolution is 9 kilometers (6 miles) per picture element. The magnetic dipole is tilted with respect to the rotational axis of Ganymede by 176°, which means that it is directed against the Jovian magnetic moment.

Moon’s radius is 1,737.1 km (1079 mi).

This image and other images and data received from Galileo are posted on the World Wide Web, on the Galileo mission home page at URLhttp://solarsystem.nasa.gov/galileo/. Scientists have also found strong evidence of an underground ocean on Ganymede.eval(ez_write_tag([[300,250],'ourplnt_com-medrectangle-4','ezslot_2',195,'0','0'])); Ganymede was discovered by Galileo Galilei on January 7, 1610. ro:Ganymede (satelit)simple:Ganymede (moon)

It takes Ganymede about seven Earth-days to orbit Jupiter.

[70] The decay of radioactive elements within rocks further heated the core, causing increased differentiation: an inner, iron–iron-sulfide core and a silicate mantle formed. It is not only the largest natural satellite of Jupiter but it is also the largest natural satellite of our … [94] The accretion of Ganymede probably took about 10,000 years,[95] much shorter than the 100,000 years estimated for Callisto. Home » Astronomy » What if Ganymede was the Earth’s second moon? You will receive a verification email shortly. [Ganymedes] was the loveliest born of … 20 Amazing Crocodile Facts [116][117] If selected, it would be launched in 2024, though this schedule might be revised and aligned with JUICE. Temperature: Daytime temperatures on the surface average minus 171 degrees Fahrenheit to minus 297 F, and night temperatures drop to -193C.

It is the ninth largest object in the Solar System and the largest without a substantial atmosphere. The south pole of Jupiter and a potential transient luminous event — a bright, unpredictable, and extremely brief flash of light — is seen in this annotated image of data acquired on April 10, 2020, from Junos UVS instrument.

It is larger in diameter than the planet Mercury but has only about half its mass. The atmosphere is far too thin to support life as we know it.

A Laplace-like resonance is similar to the current Laplace resonance among the Galilean moons with the only difference being that longitudes of the Io–Europa and Europa–Ganymede conjunctions change with rates whose ratio is a non-unity rational number. [119] However, the mission was canceled in 2005 because of budget cuts. tg:Ганимед (радиф) la:Ganymedes (satelles) They were first seen by Galileo Galilei in January 1610 and recognized by him as satellites of Jupiter in March 1610, hence the term. [23][92], Despite the presence of an iron core, Ganymede's magnetosphere remains enigmatic, particularly given that similar bodies lack the feature.
