Jupiter XLI
Aoede , also known as , is a natural satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2003. It received the temporary designation . Aoede is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 23,044,000 km in 714.657 days, at an inclination of 160° to the ecliptic (162° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.4311. It was named in March 2005 after Aœde, one of the three original Muses. Aœde was the Muse of song, and was a daughter of Zeus (Jupiter) by Mnemosyne. 2005 March 30 (Naming the moon) Aoede belongs to the |
Aoede (mythology)
In Greek mythology, Aoede ( grc, Ἀοιδή, ''Aoidē'') was one of the three original Boeotian muses, which later grew to five before the Nine Olympian Muses were named. Her sisters were Melete and Mneme. She was the muse of voice and song. According to Greek mythology, she was the daughter of Zeus, the King of the Gods, and Mnemosyne, the goddess of memory. She lends her name to the moon Jupiter XLI, also called Aoede, which orbits the planet Jupiter.

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] |
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 ...

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. ...

Retrograde Motion
Retrograde motion in astronomy is, in general, orbital or rotational motion of an object in the direction opposite the rotation of its primary, that is, the central object (right figure). It may also describe other motions such as precession or nutation of an object's rotational axis. Prograde or direct motion is more normal motion in the same direction as the primary rotates. However, "retrograde" and "prograde" can also refer to an object other than the primary if so described. The direction of rotation is determined by an inertial frame of reference, such as distant fixed stars. In the Solar System, the orbits around the Sun of all planets and most other objects, except many comets, are prograde. They orbit around the Sun in the same direction as the sun rotates about its axis, which is counterclockwise when observed from above the Sun's north pole. Except for Venus and Uranus, planetary rotations around their axes are also prograde. Most natural satellites have prograde or ...

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 ...
