Mneme (moon)
Mneme , also known as , is a retrograde irregular satellite of Jupiter. It was discovered by teams of astronomers led by Brett J. Gladman and Scott S. Sheppard in 2003, and was provisionally designated S/2003 J 21. Mneme is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 21,427,000 kilometres in 640.769 days, at an inclination of 149° to the ecliptic (148° to Jupiter's equator) with an eccentricity of 0.2214. Its average orbital speed is 2.43 km/s. It was named in March 2005 after Mneme, one of the three original Muses. 2005 March 30 (naming the moon) She is sometimes confused with , mother of the Muses (the three or the nine, de ...

Mneme (mythology)
In Greek mythology, Mneme ( grc-gre, Μνήμη, Mnḗmē) was one of the three original Boeotian muses, along with her sisters Aoede and Melete before Arche and Thelxinoë were identified, increasing the number to five. Later, the Nine Olympian Muses were named. Mneme was the muse of memory. Pausanias 9.29 (2nd Century AD) treats obscure source material already obsolete in his own day. Citing the Atthis by Hegesinus — a poem no longer extant for Pausanias but cited by Callippus of Corinth (whose history of Orchomenus is no longer extant for us) — Pausanias records that anciently a group of three Boeotian Muses was venerated on Mt Helicon. These were displaced by a cult of nine Muses. Namesake * Mneme Lake in Antarctica is named after the muse. * Jupiter's moon Mneme is named after the muse See also * Meme * Memo (other) * Memento (other) A memento is a keepsake or souvenir of remembrance.

Irregular Satellites
In astronomy, an irregular moon, irregular satellite or irregular natural satellite is a natural satellite following a distant, inclined, and often eccentric and retrograde orbit. They have been captured by their parent planet, unlike regular satellites, which formed in orbit around them. Irregular moons have a stable orbit, unlike temporary satellites which often have similarly irregular orbits but will eventually depart. The term does not refer to shape as Triton is a round moon, but is considered irregular due to its orbit. As of December 2022, 149 irregular moons are known, orbiting all four of the outer planets (Jupiter, Saturn, Uranus and Neptune). The largest of each planet are Himalia of Jupiter, Phoebe of Saturn, Sycorax of Uranus, and Triton of Neptune. It is currently thought that the irregular satellites were captured from heliocentric orbits near their current locations, shortly after the formation of their parent planet. An alternative theory, that they originated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moons Of Jupiter
There are 82 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 other sexual partners) 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 78 known moons and the rings together composing just 0.003% of the total orbiting mass. Of Jupiter's moons, eight are regular satellites with prograde and nearly circular orbits that are not greatly inclined wit ...

Zeus
Zeus or , , ; grc, Δῐός, ''Diós'', label=Genitive case, genitive Aeolic Greek, Boeotian Aeolic and Doric Greek#Laconian, Laconian grc-dor, Δεύς, Deús ; grc, Δέος, ''Déos'', label=Genitive case, genitive el, Δίας, ''Días'' () is the sky father, sky and thunder god in ancient Greek religion, who rules as king of the gods on Mount Olympus. His name is cognate with the first element of his ancient Roman religion, Roman interpretatio graeca, equivalent Jupiter (mythology), Jupiter.''Larousse Desk Reference Encyclopedia'', The Book People, Haydock, 1995, p. 215. His mythology and powers are similar, though not identical, to those of Indo-European deities such as Jupiter, Perkūnas, Perun, Indra, Dyaus, and Zojz (deity), Zojz. Entry: "Dyaus" Zeus is the child of Cronus and Rhea (mythology), Rhea, the youngest of his siblings to be born, though sometimes reckoned the eldest as the others required disgorging from Cronus's stomach.

Mnemosyne
In Greek mythology and ancient Greek religion, Mnemosyne (; grc, Μνημοσύνη, ) is the goddess of memory and the mother of the nine Muses by her nephew Zeus. In the Greek tradition, Mnemosyne is one of the Titans, the twelve divine children of the earth-goddess Gaia and the sky-god Uranus. The term ''Mnemosyne'' is derived from the same source as the word ''mnemonic'', that being the Greek word ''mnēmē'', which means "remembrance, memory". Family A Titaness, Mnemosyne is the daughter of Uranus and Gaia. Mnemosyne became the mother of the nine Muses, fathered by her nephew, Zeus: * Calliope (epic poetry) * Clio (history) * Euterpe (music and lyric poetry) * Erato (love poetry) * Melpomene (tragedy) * Polyhymnia (hymns) * Terpsichore (dance) * Thalia (comedy) * Urania (astronomy) Hyginus in his ''Fabulae'' gives Mnemosyne a different parentage, where she was the daughter of Zeus and Clymene.

Muse
In ancient Greek religion and mythology, the Muses ( grc, Μοῦσαι, Moûsai, el, Μούσες, Múses) are the inspirational goddesses of literature, science, and the arts. They were considered the source of the knowledge embodied in the poetry, lyric songs, and myths that were related orally for centuries in ancient Greek culture. Melete, Aoede, and Mneme are the original Boeotian Muses, and Calliope, Clio, Erato, Euterpe, Melpomene, Polyhymnia, Terpsichore, Thalia, and Urania are the nine Olympian Muses. In modern figurative usage, a Muse may be a source of artistic inspiration. Etymology The word ''Muses'' ( grc, Μοῦσαι, Moûsai) perhaps came from the o-grade of the Proto-Indo-European root (the basic meaning of which is 'put in mind' in verb formations with transitive function and 'have in mind' in those with intransitive function), or from root ('to tower, mountain') since all the most important cult-centres of the Muses were on mountains or hills. ...

Eccentricity (orbit)
In astrodynamics, the orbital eccentricity of an astronomical object is a dimensionless parameter that determines the amount by which its orbit around another body deviates from a perfect circle. A value of 0 is a circular orbit, values between 0 and 1 form an elliptic orbit, 1 is a parabolic escape orbit (or capture orbit), and greater than 1 is a hyperbola. The term derives its name from the parameters of conic sections, as every Kepler orbit is a conic section. It is normally used for the isolated two-body problem, but extensions exist for objects following a rosette orbit through the Galaxy. Definition In a two-body problem with inverse-square-law force, every orbit is a Kepler orbit. The eccentricity of this Kepler orbit is a non-negative number that defines its shape. The eccentricity may take the following values: * circular orbit: ''e'' = 0 * elliptic orbit: 0 < ''e'' < 1 * [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ecliptic
The ecliptic or ecliptic plane is the orbital plane of the Earth around the Sun. From the perspective of an observer on Earth, the Sun's movement around the celestial sphere over the course of a year traces out a path along the ecliptic against the background of stars. The ecliptic is an important reference plane and is the basis of the ecliptic coordinate system. Sun's apparent motion The ecliptic is the apparent path of the Sun throughout the course of a year. Because Earth takes one year to orbit the Sun, the apparent position of the Sun takes one year to make a complete circuit of the ecliptic. With slightly more than 365 days in one year, the Sun moves a little less than 1° eastward every day. This small difference in the Sun's position against the stars causes any particular spot on Earth's surface to catch up with (and stand directly north or south of) the Sun about four minutes later each day than it would if Earth did not orbit; a day on Earth is therefore 24 hours ...
