The Galilean moons are the four largest moons of Jupiter—Io, Europa, Ganymede, and Callisto. They were first seen by Galileo Galilei in December 1609 or January 1610, and recognized by him as satellites of Jupiter in March 1610. They were the first objects found to orbit a planet other than the Earth.
Ganymede, a satellite of Jupiter, is the largest and most massive of the Solar System's moons. The ninth-largest object of the Solar System, it is the largest without a substantial atmosphere. It has a diameter of 5,268 km (3,273 mi), making it 26 percent larger than the planet Mercury by volume, although it is only 45 percent as massive. Possessing a metallic core, it has the lowest moment of inertia factor of any solid body in the Solar System and is the only moon known to have a magnetic field. Outward from Jupiter, it is the seventh satellite and the third of the Galilean moons, the first group of objects discovered orbiting another planet. Ganymede orbits Jupiter in roughly seven days and is in a 1:2:4 orbital resonance with the moons Europa and Io, respectively.
There are 80 known moons of Jupiter, not counting a number of moonlets likely shed from the inner moons. All together, they form a satellite system which is called the Jovian system. The most massive of the moons are the four Galilean moons: Io, Europa, Ganymede, and Callisto, which were independently discovered in 1610 by Galileo Galilei and Simon Marius and were the first objects found to orbit a body that was neither Earth nor the Sun. Much more recently, beginning in 1892, dozens of far smaller Jovian moons have been detected and have received the names of lovers or daughters of the Roman god Jupiter or his Greek equivalent Zeus. The Galilean moons are by far the largest and most massive objects to orbit Jupiter, with the remaining 76 known moons and the rings together composing just 0.003% of the total orbiting mass.
A mantle is a layer inside a planetary body bounded below by a core and above by a crust. Mantles are made of rock or ices, and are generally the largest and most massive layer of the planetary body. Mantles are characteristic of planetary bodies that have undergone differentiation by density. All terrestrial planets, a number of asteroids, and some planetary moons have mantles.
A crater chain is a line of craters along the surface of an astronomical body. The descriptor term for crater chains is catena, plural catenae, as specified by the International Astronomical Union's rules on planetary nomenclature.
Aquarius (♒︎) is the eleventh astrological sign in the zodiac, originating from the constellation Aquarius. Under the tropical zodiac, the Sun is in the Aquarius sign between about January 21 and about February 20, while under the sidereal Zodiac, the sun is in Aquarius from approximately February 15 to March 14, depending on the leap year.
USS Ganymede (AK-104) was an Crater-class cargo ship commissioned by the US Navy for service in World War II. She was responsible for delivering troops, goods and equipment to locations in the war zone. Named after the largest of the moons of Jupiter, Ganymede was the only ship of the Navy to bear this name.
Ganymede most commonly refers to:
In Greek mythology, Ganymede or Ganymedes is a divine hero whose homeland was Troy. Homer describes Ganymede as the most beautiful of mortals, abducted by the gods, to serve as Zeus's cup-bearer in Olympus.
[Ganymedes] was the loveliest born of the race of mortals, and therefore
the gods caught him away to themselves, to be Zeus' wine-pourer,
for the sake of his beauty, so he might be among the immortals.
Rosalind is the heroine and protagonist of the play As You Like It (1600) by William Shakespeare. In the play, she disguises herself as a male shepherd named Ganymede. Many actors have portrayed Rosalind, including Sarah Wayne Callies, Maggie Smith, Elizabeth Bergner, Vanessa Redgrave, Helena Bonham Carter, Helen Mirren, Patti LuPone, Helen McCrory, Bryce Dallas Howard, and Adrian Lester.
Polona Juh is a Slovenian actress. She is the daughter of the Slovenian actors Mojca Ribič and Boris Juh. After finishing her studies at High School for Ballet, she entered to study acting at the Academy for Theatre, Radio, Film and Television, where she graduated. Since 1995, she is a permanent member of Slovenian National Theatre Drama in Ljubljana.
The Europa Jupiter System Mission – Laplace (EJSM-Laplace) was a proposed joint NASA/ESA uncrewed space mission slated to launch around 2020 for the in-depth exploration of Jupiter's moons with a focus on Europa, Ganymede and Jupiter's magnetosphere. The mission would have comprised at least two independent elements, NASA's Jupiter Europa Orbiter (JEO) and ESA's Jupiter Ganymede Orbiter (JGO), to perform coordinated studies of the Jovian system.
United States v. Kilbride, 584 F.3d 1240 is a case from the United States Court of Appeals for the Ninth Circuit rejecting an appeal from two individuals convicted of violating the Can Spam Act and US obscenity law. The defendants were appealing convictions on 8 counts from the District Court of Arizona for distributing pornographic spam via email. The second count which the defendants were found guilty of involved the falsification of the "From" field of email headers, which is illegal to do multiple times in commercial settings under 18 USC § 1037(a)(3). The case is particularly notable because of the majority opinion on obscenity, in which Judge Fletcher writes an argument endorsing the use of a national community obscenity standard for the internet.
Laplace-P is a proposed orbiter and lander by the Russian Federal Space Agency designed to study the Jovian moon system and explore Ganymede with a lander.
The Jupiter Icy Moons Explorer (JUICE) is an interplanetary spacecraft in development by the European Space Agency (ESA) with Airbus Defence and Space as the main contractor. The mission will study three of Jupiter's Galilean moons: Ganymede, Callisto, and Europa all of which are thought to have significant bodies of liquid water beneath their surfaces, making them potentially habitable environments.
