Philophrosyne (moon)
Philophrosyne ( or ), also Jupiter LVIII and provisionally 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, ''et al.'' in 2003, but then lost. It was recovered in 2017 and given its permanent designation that year. Characteristics Philophrosyne is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 22,721,000 km in 699.676 days, at an inclination of 142° to the ecliptic (142° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.0932. It belongs to the Pasiphae group, retrograde irregular moons that orbit Jupiter between 22.8 and 24.1 Gm, at inclinations of roughly 150-155°. Name The moon was named in 2019 after Philophrosyne (Φιλοφροσύνη), the ancient Greek spirit of welcome, friendliness, and kindness, the daughter of Hephaestus and Aglaea and granddaughter of Zeus. The name originated from a naming contest held on Tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philophrosyne
Philophrosyne was the ancient Greek female spirit of welcome, friendliness, and kindness. Her sisters were Euthenia, Eupheme, and Eucleia. Along with her sisters, she was regarded as a member of the younger Charites. According to the Orphic fragments, Philophrosyne was the daughter of Hephaestus and Aglaia ''Aglaia'' is a genus of 117 species of woody dioecious trees belonging to the Mahogany family (Meliaceae). These trees occur in the subtropical and tropical forests of Southeast Asia, Northern Australia and the Pacific. Some species are impo ....

Hephaestus
Hephaestus (; eight spellings; grc-gre, Ἥφαιστος, Hḗphaistos) is the Greek god of blacksmiths, metalworking, carpenters, craftsmen, artisans, sculptors, metallurgy, fire (compare, however, with Hestia), and volcanoes.Walter Burkert, ''Greek Religion'' 1985: III.2.ii; see coverage of Lemnos-based traditions and legends at Mythic Lemnos Hephaestus's Roman counterpart is Vulcan. In Greek mythology, Hephaestus was either the son of Zeus and Hera or he was Hera's parthenogenous child. He was cast off Mount Olympus by his mother Hera because of his lameness, the result of a congenital impairment; or in another account, by Zeus for protecting Hera from his advances (in which case his lameness would have been the result of his fall rather than the reason for it). As a smithing god, Hephaestus made all the weapons of the gods in Olympus. He served as the blacksmith of the gods, and was worshipped in the manufacturing and industrial centres of Greece, particularly Athen ...

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 ...

Astrogeology Research Program
The Astrogeology Science Center is the entity within the United States Geological Survey concerned with the study of planetary geology and planetary cartography. It is housed in the Shoemaker Building in Flagstaff, Arizona. The Center was established in 1963 by Eugene Merle Shoemaker to provide lunar geologic mapping and to assist in training astronauts destined for the Moon as part of the Apollo program. Since its inception, the Astrogeology Science Center has participated in processing and analyzing data from various missions to the planetary bodies in the Solar System, assisting in finding potential landing sites for exploration vehicles, mapping our neighboring planets and their moons, and conducting research to better understand the origins, evolutions, and geologic processes operating on these bodies. The Early Days Gene Shoemaker founded the Astrogeology Research Program August 25, 1960. The research program started out as the ''Astrogeologic Studies Group'' at the Uni ...

Eupheme (moon)
Eupheme , also Jupiter LX, originally known as , is an outer natural satellite of Jupiter, 2 km in diameter. Discovery It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2003. The moon was lost following its discovery in 2003. It was recovered in 2017 and given its permanent designation that year. Name It was named in 2019 after Eupheme, the ancient Greek spirit of words of good omen, praise, acclaims, shouts of triumph, and applause, the daughter of Hephaestus and Aglaea and granddaughter of Zeus. The name was suggested by Twitter user Lunartic (@iamalunartic) in a naming contest held by the Carnegie Institute on the social network who concurrently helped in naming another Jovian moon Philophrosyne. Orbit Eupheme orbits Jupiter at an average distance of 19,622 Mm in 628.06 days, at an inclination of 146° to the ecliptic (146° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.2507.

Aglaea
Aglaea () or Aglaïa (; grc, Ἀγλαΐα, lit=festive radiance) is one of the three ''Charites'' or ''Gratiae'' (Graces) in Greek mythology. Family According to Hesiod, Aglaea is the youngest of the Charites, the three daughters of Zeus and the Oceanid Eurynome. The mythographer Apollodorus, in constrast, calls them the children of Zeus by Eunomia, the goddess of good order and lawful conduct. Aglaea's two sisters are Euphrosyne, the goddess of joy or mirth, and Thalia, the goddess of festivity and rich banquets. Together they are known as the Charites in Greek mythology or the ''Gratiae'' (Graces) in Roman mythology, and they were responsible for overseeing all feasts and dances. They were part of the retinue of Aphrodite with Aglaea sometimes acting as her messenger. Aglaea was married to Hephaestus, typically seen as after his divorce from Aphrodite, and by him she became mother of Eucleia ("Good Repute"), Eupheme ("Acclaim"), Euthenia ("Prosperity"), and Philophrosyn ...

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] |
