Gerd (moon)
Gerd (Saturn LVII), provisionally known as S/2004 S 25, is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, and Jan Kleyna on October 7, 2019 from observations taken between December 12, 2004 and March 22, 2007. It was given its permanent designation in August 2021. On 24 August 2022, it was officially named after Gerðr, a jötunn from Norse mythology Norse, Nordic, or Scandinavian mythology, is the body of myths belonging to the North Germanic peoples, stemming from Old Norse religion and continuing after the Christianization of Scandinavia as the Nordic folklore of the modern period. The .... She is married to Freyr and the personification of fertile soil. Gerd is about 4 kilometres in diameter, and orbits Saturn at an average distance of 21.174 Gm in 1150.69 days, at an inclination of 173° to the ecliptic, in a retrograde direction and with an eccentricity of 0.442.

Gerðr
In Norse mythology, Gerðr (Old Norse: ; "fenced-in"Orchard (1997:54).) is a jötunn, Æsir, goddess, and the wife of the god Freyr. Gerðr is attested in the ''Poetic Edda'', compiled in the 13th century from earlier traditional sources; the ''Prose Edda'' and ''Heimskringla'', written in the 13th century by Snorri Sturluson; and in the poetry of skalds. ''Gerðr'' is sometimes modernly anglicized as Gerd or Gerth. In both the ''Poetic Edda'' and the ''Prose Edda'', Freyr sees Gerðr from a distance, becomes deeply lovesick at the sight of her shimmering beauty, and has his servant Skírnir go to Jötunheimr (where Gerðr and her father Gymir (father of Gerðr), Gymir reside) to gain her love. In the ''Poetic Edda'' Gerðr initially refuses, yet after a series of threats by Skírnir she is forced to yield. In the ''Prose Edda'', no mention of threats is made. In both sources, Gerðr agrees to meet Freyr at a fixed time at the location of Barri and, after Skírnir returns with Ger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saturn
Saturn is the sixth planet from the Sun and the second largest in the Solar System, after Jupiter. It is a gas giant, with an average radius of about 9 times that of Earth. It has an eighth the average density of Earth, but is over 95 times more massive. Even though Saturn is almost as big as Jupiter, Saturn has less than a third its mass. Saturn orbits the Sun at a distance of , with an orbital period of 29.45 years. Saturn's interior is thought to be composed of a rocky core, surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and an outer layer of gas. Saturn has a pale yellow hue, due to ammonia crystals in its upper atmosphere. An electrical current in the metallic hydrogen layer is thought to give rise to Saturn's planetary magnetic field, which is weaker than Earth's, but has a magnetic moment 580 times that of Earth because of Saturn's greater size. Saturn's magnetic field strength is about a twen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norse Group
The Norse group is a large group of Retrograde and prograde motion, retrograde irregular satellites of Saturn. Their semi-major axis, semi-major axes range between 12 and 27 Gm, their inclinations between 136° and 178° and their Orbital eccentricity, eccentricities between 0.06 and 0.63. Unlike the Inuit group, Inuit and Gallic groups, the orbital parameters are widely dispersed and the group is likely to be composed from a number of subgroups with more homogeneous orbital and physical parameters. The International Astronomical Union (IAU) reserves names taken from Norse mythology (mostly giants) for the satellites, with the exception of Phoebe (Greek mythology), the largest, which was discovered long before the others. The discovery of 17 new satellites in this group was announced in October 2019. A team led by Scott S. Sheppard using the Subaru Telescope at Mauna Kea discovered 20 new moons, each about in diameter. 17 of these are thought to fit into the Norse group. One of t ...

Natural Satellite
A natural satellite is, in the most common usage, an astronomical body that orbits a planet, dwarf planet, or small Solar System body (or sometimes another natural satellite). Natural satellites are colloquially referred to as moons, a derivation from the Moon of Earth. In the Solar System, there are six planetary satellite systems containing 418 known natural satellites altogether. Seven objects commonly considered dwarf planets by astronomers are also known to have natural satellites: , Pluto, Haumea, , Makemake, , and Eris. As of January 2022, there are 447 other minor planets known to have natural satellites. A planet usually has at least around 10,000 times the mass of any natural satellites that orbit it, with a correspondingly much larger diameter. The Earth–Moon system is a unique exception in the Solar System; at 3,474 kilometres (2,158 miles) across, the Moon is 0.273 times the diameter of Earth and about of its mass. The next largest ratios are the N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David C
David (; , "beloved one") was a king of ancient Israel and Judah and the third king of the United Monarchy, according to the Hebrew Bible and Old Testament. The Tel Dan stele, an Aramaic-inscribed stone erected by a king of Aram-Damascus in the late 9th/early 8th centuries BCE to commemorate a victory over two enemy kings, contains the phrase (), which is translated as " House of David" by most scholars. The Mesha Stele, erected by King Mesha of Moab in the 9th century BCE, may also refer to the "House of David", although this is disputed. According to Jewish works such as the '' Seder Olam Rabbah'', '' Seder Olam Zutta'', and '' Sefer ha-Qabbalah'' (all written over a thousand years later), David ascended the throne as the king of Judah in 885 BCE. Apart from this, all that is known of David comes from biblical literature, the historicity of which has been extensively challenged,Writing and Rewriting the Story of Solomon in Ancient Israel; by Isaac Kalimi; page 3 ...

Norse Mythology
Norse, Nordic, or Scandinavian mythology, is the body of myths belonging to the North Germanic peoples, stemming from Old Norse religion and continuing after the Christianization of Scandinavia as the Nordic folklore of the modern period. The North Germanic languages, northernmost extension of Germanic mythology and stemming from Proto-Germanic folklore, Norse mythology consists of tales of various deities, beings, and heroes derived from numerous sources from both before and after the pagan period, including medieval manuscripts, archaeological representations, and folk tradition. The source texts mention numerous gods such as the thunder-god Thor, the Huginn and Muninn, raven-flanked god Odin, the goddess Freyja, and List of Germanic deities, numerous other deities. Most of the surviving mythology centers on the plights of the gods and their interaction with several other beings, such as humanity and the jötnar, beings who may be friends, lovers, foes, or family members of ...

Freyr
Freyr (Old Norse: 'Lord'), sometimes anglicized as Frey, is a widely attested Æsir, god in Norse mythology, associated with kingship, fertility, peace, prosperity, fair weather, and good harvest. Freyr, sometimes referred to as Yngvi-Freyr, was especially associated with Sweden and seen as an ancestor of the Yngling, Swedish royal house. According to Adam of Bremen, Freyr was associated with peace and pleasure, and was represented with a phallus, phallic statue in the Temple at Uppsala. According to Snorri Sturluson, Freyr was "the most renowned of the æsir", and was venerated for good harvest and peace. In the mythological stories in the Icelandic books the ''Poetic Edda'' and the ''Prose Edda'', Freyr is presented as one of the Vanir, the son of the god Njörðr and Sister-wife of Njörðr, his sister-wife, as well as the twin brother of the goddess Freyja. The gods gave him Álfheimr, the realm of the Álfar, Elves, as a teething present. He rides the shining Norse dwarves, ... [...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 an orbit that is irregular in some of the following ways: Distant; orbital inclination, inclined; orbital eccentricity, highly elliptical; Retrograde and prograde motion, retrograde. They have often been Asteroid capture, captured by their parent planet, unlike regular satellites 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; Triton (moon), Triton, for example, is a planetary-mass moon, round moon but is considered irregular due to its orbit and origins. , 356 irregular moons are known, orbiting all four of the outer planets (Jupiter, Saturn, Uranus, and Neptune). The largest of each planet are Himalia (moon), Himalia of Jupiter, Phoebe (moon), Phoebe of Saturn, Sycorax (moon), Sycorax of Uranus, and Triton (moon), ...
