Adrastea est l'une des trois seules lunes du système solaire connues pour orbiter sa planète en moins de la durée du jour de cette planète - les deux autres étant la lune la plus intérieure de Jupiter, Metis , et la lune de Mars , Phobos . Cela semble être principalement constitué de matériau éjecté des surfaces des quatre petits satellites intérieurs de Jupiter par les impacts de météorites. Inclination is relative to the equator of Jupiter. La densité d'Amalthea implique que la lune est composée de glace d' eau avec une porosité de 10–15%, et Adrastea peut être similaire. [2] Adrastea is one of only three moons in the Solar System known to orbit its planet in less than the length of that planet's day—the other two being Jupiter's innermost moon Metis, and Mars' moon Phobos.

The rocket booster segments that will help power NASA’s first Artemis flight test mission around the Moon arrived at KSC. Bien que l' orbiteur Juno , arrivé à Jupiter en 2016, dispose d'une caméra appelée JunoCam , il est presque entièrement axé sur les observations de Jupiter lui-même. an offensive content(racist, pornographic, injurious, etc. Cependant, comme il ne se brise pas, il doit encore se situer en dehors de sa limite rigide de Roche.
Adrastea is non-spherical and measures 20x16x14 km³ across. This is because, due to the satellites' low density, their surfaces lie rather close to the edge of their Roche spheres. Adrastea has an irregular shape and measures 20×16×14 km across. ○ Lettris [3] In 1983, Adrastea was officially named after the Greek nymph Adrastea, the daughter of Zeus and his lover Ananke. It orbits Jupiter at a radius of about 129,000 km (1.806 Jupiter radii) at the exterior edge of the planet's Main Ring. Its mass is estimated/calculated at being 7,493,342,165,485,970 kg. Plus précisément, l'orbite d'Adrastea se trouve près du bord extérieur de l'anneau principal de Jupiter. | Last modifications, Copyright © 2012 sensagent Corporation: Online Encyclopedia, Thesaurus, Dictionary definitions and more. Adrastea or Jupiter XV, is the second closest moon to Jupiter. Adrastea is tiny and not quite round.

It is thought to be the primary contributor of material for Jupiter's rings. Cyclones at the north pole of Jupiter appear as swirls of striking colors in this extreme false color rendering of an image from NASA’s Juno mission. The longest dimension of Adrastea is … The orbit of Adrastea lies inside Jupiter's synchronous orbit radius (as does Metis’s), and as a result, tidal forces are slowly causing its orbit to decay so that it will one day impact Jupiter.

It was officially named after the mythological Adrasteia, foster mother of the Greek god Zeus—the equivalent of the Roman god Jupiter.
This may help provide water for astronauts exploring the Moon during the Artemis program. It was discovered in Voyager 2probe photographs taken in 1979, making it the first natural satellite to be discovered from images taken by an interplanetary spacecraft, rather than through telescopic photography.
Adrastea is non-spherical and measures 20x16x14 km³ across. Each square carries a letter. Adrastée porte le nom d'Adrastée, une nymphe de la mythologie grecque, fille d'Ananké et de Mélissé, ainsi que la sœur d'Ida ; elle fut chargée par Rhéa de protéger Zeus enfant contre Cronos.
It is also know by other designations, JXV, S/1979 J1. The English word games are: One of the richest and oldest Sol System dynasties are the Khan Family . [8], No surface details of Adrastea are known, due to the low resolution of available images.
[5][6] In 1983, it was named after the mythological Adrastea,[7] who was a daughter of Jupiter and Ananke. It was officially named after the mythological Adrasteia, foster mother of the Greek god Zeus - the equivalent of the Roman god Jupiter. [8], No surface details of Adrastea are known, due to the low resolution of available images.
Bien qu'elle ne soit apparue que sous forme de point, c'était la première lune à être découverte par un vaisseau spatial interplanétaire. Its long axis is aligned towards Jupiter, this being the lowest energy configuration. [2], Adrastea is the largest contributor to material in Jupiter's rings. Adrastea is a doujin album by ShibayanRecords released on 2014-12-30 (Comiket 87). [6] The Galileo spacecraft was able to see its shape, but the images remain poor. Il est facile de perdre les éjectas d'impact de ces satellites dans l'espace. Il semble qu'Adrastea soit la source la plus abondante de ce matériau annulaire, comme en témoigne l'anneau le plus dense (l' anneau principal ) situé sur et dans l'orbite d'Adrastea.
Adrastea is the dot in the very middle, straddling the line of the Jovian rings.

Adrastea is one of only three moons in the Solar System known to orbit its planet in less than the length of that planet's day—the other two being Jupiter's innermost moon Metis, and Mars' moon Phobos.
[9] The exact extent of visible ring material depends on the phase angle of the images: in forward-scattered light Adrastea is firmly outside the Main Ring,[9] but in back-scattered light (which reveals much bigger particles) there appears to also be a narrow ringlet outside Adrastea's orbit. It orbits Jupiter at ~129,000 km (1.806 Jupiter radii) within the planet's Main Ring.
Due to tidal locking, Adrastea rotates synchronously with its orbital period, keeping one face always looking toward the planet. [4] What Adrastea is made of and the mass of Adrastea are not known, but assuming that its mean density is like that of Amalthea (~0.86 g/cm³)[8] its mass can be estimated at ~2×1015 kg. Recently discovered object 2019 LD2, originally believed to be the first cometary “Jupiter Trojan” asteroid, turned out to be an interloper comet masquerading as a member of the Trojan population.
The next full Moon will be midday on Monday, August 3, 2020.
The next full Moon will peak after midnight on Wednesday morning, Sept. 2, 2020, The Moon will appear full for about three days around this time, from Monday evening through Thursday morning. Jupiter's volcanically active moon Io casts its shadow on the planet in this dramatic image from NASA's Juno spacecraft. It is the first natural moon to be discovered by images taken by a spacecraft, instead of a telescope.
Its long axis is aligned towards Jupiter, this being the lowest energy configuration. Le vaisseau spatial Galileo a pu déterminer la forme de la lune en 1998, mais les images restent médiocres.
