Dactyl (moon)
(243) Ida I Dactyl ( ) is a tiny asteroid moon (1.6 km in diameter) that orbits asteroid 243 Ida. It was imaged by the ''Galileo'' spacecraft on August 28, 1993; Dactyl was discovered while examining the delayed image downloads from Galileo on February 17, 1994. It was provisionally designated S/1993 (243) 1. The satellite was named after the mythical creatures called dactyls who lived on Mount Ida according to Greek mythology. Dactyl orbits Ida with a period of 1.54 days at an average distance of 108 km, with an inclination of 9° to Ida's equator. The origins of Dactyl are unclear, but two main hypotheses exist. The first is that Dactyl and Ida formed at the same time, and the second is that Dactyl was knocked loose by a later impact. Dactyl was the first asteroid moon discovered. Its discovery settled the long debate over the existence of asteroid moons. See also *List of geological features on 243 Ida and Dactyl This is a list of named geological features on ...

Dactyl (mythology)
In Greek mythology, the Dactyls or Daktyloi (; from grc, Δάκτυλοι ''Dáktuloi'' "fingers") were the archaic mythical race of male beings associated with the Great Mother, whether as Cybele or Rhea. Their numbers vary, but often they were ten spirit-men so like the three Korybantes or the Cabeiri that they were often interchangeable. The Dactyls were both ancient smiths and healing magicians. In some myths, they are in Hephaestus' employ, and they taught metalworking, mathematics, and the alphabet to humans. When Ankhiale knew her time of delivery was come, she went to Psychro Cave on Cretan Mount Ida. As she squatted in labor she dug her fingers into the earth (Gaia), which brought forth these ''daktyloi Idaioi'' ( "Idaean fingers"), thus often ten in number, or sometimes multiplied into a race of ten tens. Three is just as often given as their number. They are sometimes instead numbered as thirty-three. When Greeks offered a most solemn oath, often they would press ...

Equator
The equator is a circle of latitude, about in circumference, that divides Earth into the Northern and Southern hemispheres. It is an imaginary line located at 0 degrees latitude, halfway between the North and South poles. The term can also be used for any other celestial body that is roughly spherical. In spatial (3D) geometry, as applied in astronomy, the equator of a rotating spheroid (such as a planet) is the parallel (circle of latitude) at which latitude is defined to be 0°. It is an imaginary line on the spheroid, equidistant from its poles, dividing it into northern and southern hemispheres. In other words, it is the intersection of the spheroid with the plane perpendicular to its axis of rotation and midway between its geographical poles. On and near the equator (on Earth), noontime sunlight appears almost directly overhead (no more than about 23° from the zenith) every day, year-round. Consequently, the equator has a rather stable daytime temperature throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greek Mythology
A major branch of classical mythology, Greek mythology is the body of myths originally told by the ancient Greeks, and a genre of Ancient Greek folklore. These stories concern the origin and nature of the world, the lives and activities of deities, heroes, and mythological creatures, and the origins and significance of the ancient Greeks' own cult and ritual practices. Modern scholars study the myths to shed light on the religious and political institutions of ancient Greece, and to better understand the nature of myth-making itself. The Greek myths were initially propagated in an oral-poetic tradition most likely by Minoan and Mycenaean singers starting in the 18th century BC; eventually the myths of the heroes of the Trojan War and its aftermath became part of the oral tradition of Homer's epic poems, the ''Iliad'' and the ''Odyssey''. Two poems by Homer's near contemporary Hesiod, the '' Theogony'' and the '' Works and Days'', contain accounts of the genesi ...

Mount Ida
In Greek mythology, two sacred mountains are called Mount Ida, the "Mountain of the Goddess": Mount Ida (Crete), Mount Ida in Crete, and Mount Ida (Turkey), Mount Ida in the ancient Troad region of western Anatolia (in modern-day Turkey), which was also known as the ''Mount Ida (Turkey), Phrygian Ida'' in classical antiquity and is mentioned in the ''Iliad'' of Homer and the ''Aeneid'' of Virgil. Both are associated with the mother goddess in the deepest layers of pre-Greek myth, in that Mount Ida in Anatolia was sacred to Cybele, who is sometimes called ''Mater Idaea'' ("Idaean Mother"), while Rhea (mythology), Rhea, often identified with Cybele, put the infant Zeus to nurse with Amalthea (mythology), Amaltheia at Mount Ida in Crete. Thereafter, his birthplace was sacred to Zeus, the king and father of Greek gods and goddesses. Etymology The term ''Ida'' (Ἴδη) is of unknown origin. Instances of ''i-da'' in Linear A probably refer to the mountain in Crete. Three inscriptions b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mythology
Myth is a folklore genre consisting of narratives that play a fundamental role in a society, such as foundational tales or origin myths. Since "myth" is widely used to imply that a story is not objectively true, the identification of a narrative as a myth can be highly controversial. Many adherents of religions view their own religions' stories as truth and so object to their characterization as myth, the way they see the stories of other religions. As such, some scholars label all religious narratives "myths" for practical reasons, such as to avoid depreciating any one tradition because cultures interpret each other differently relative to one another. Other scholars avoid using the term "myth" altogether and instead use different terms like "sacred history", "holy story", or simply "history" to avoid placing pejorative overtones on any sacred narrative. Myths are often endorsed by secular and religious authorities and are closely linked to religion or spirituality. Many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Galileo (spacecraft)
''Galileo'' was an American robotic space probe that studied the planet Jupiter and its moons, as well as the asteroids Gaspra and Ida. Named after the Italian astronomer Galileo Galilei, it consisted of an orbiter and an entry probe. It was delivered into Earth orbit on October 18, 1989, by , during STS-34. ''Galileo'' arrived at Jupiter on December 7, 1995, after gravitational assist flybys of Venus and Earth, and became the first spacecraft to orbit an outer planet. The Jet Propulsion Laboratory built the ''Galileo'' spacecraft and managed the ''Galileo'' program for NASA. West Germany Messerschmitt-Bölkow-Blohm supplied the propulsion module. NASA's Ames Research Center managed the atmospheric probe, which was built by Hughes Aircraft Company. At launch, the orbiter and probe together had a mass of and stood tall. Spacecraft are normally stabilized either by spinning around a fixed axis or by maintaining a fixed orientation with reference to the Sun and a star. ' ...
