Cilix (crater)
Cilix is a small crater on Europa that serves as the reference point for the moon's system of longitude. The longitude of Cilix's center is defined as being 182° W, thus establishing the moon's prime meridian. It is named after Cilix Cilix (; Ancient Greek: Κίλιξ ''Kílix'') was, according to Greek mythology, a Phoenician prince as the son of King Agenor and Telephassa or Argiope. Etymology In her book ''Who's Who in Classical Mythology'', author Adrian Room writes an ..., the brother of Europa Cilix is about 15 km in diameter.

Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become ...

Europa (moon)
Europa , or Jupiter II, is the smallest of the four Galilean moons orbiting Jupiter, and the sixth-closest to the planet of all the 80 known moons of Jupiter. It is also the sixth-largest moon in the Solar System. Europa was discovered in 1610 by Galileo Galilei and was named after Europa, the Phoenician mother of King Minos of Crete and lover of Zeus (the Greek equivalent of the Roman god Jupiter). Slightly smaller than Earth's Moon, Europa is primarily made of silicate rock and has a water-ice crust and probably an iron–nickel core. It has a very thin atmosphere, composed primarily of oxygen. Its white- beige surface is striated by light tan cracks and streaks, but craters are relatively few. In addition to Earth-bound telescope observations, Europa has been examined by a succession of space-probe flybys, the first occurring in the early 1970s. In September 2022, the ''Juno'' spacecraft flew within about 200 miles of Europa for a more recent close-up view. Europa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longitude
Longitude (, ) is a geographic coordinate that specifies the east– west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians are semicircular lines running from pole to pole that connect points with the same longitude. The prime meridian defines 0° longitude; by convention the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, England on the island of Great Britain. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the Earth's rotation, there is a close connection between longitude and time measurement. Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the differing position in relation to the Sun. Comparing local time to an absolute measure of ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prime Meridian
A prime meridian is an arbitrary meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides a spheroid, like the Earth, into two hemispheres: the Eastern Hemisphere and the Western Hemisphere (for an east-west notational system). For Earth's prime meridian, various conventions have been used or advocated in different regions throughout history. The Earth's current international standard prime meridian is the IERS Reference Meridian. It is derived, but differs slightly, from the Greenwich Meridian, the previous standard. A prime meridian for a planetary body not tidally locked (or at least not in synchronous rotation) is entirely arbitrary, unlike an equator, which is determined by the axis of rotation. However, for celestial objects that are tidally locked (more specifically, synchronous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cilix
Cilix (; Ancient Greek: Κίλιξ ''Kílix'') was, according to Greek mythology, a Phoenician prince as the son of King Agenor and Telephassa or Argiope. Etymology In her book ''Who's Who in Classical Mythology'', author Adrian Room writes an entry on Cilix describing the nature of the name's etymology. Room writes that "we can perhaps see in his name a blend of ceras, 'horn' and helix, 'twisted', or even a link with cyllos, 'crooked'". This is referring to the horns of Zeus in the form of a white bull, who carried off Cilix's sister Europa to the coast of Crete. Cilicia's etymology is broken up into two parts according to the two parts of its terrain. Cilicia Trachea is "rugged Cilicia", in Greek Κιλικία Τραχεῖα; it is also the Assyrian ''Hilakku'', classical "Cilicia". Cilicia Pedias is "flat Cilicia", in Ancient Greek: Κιλικία Πεδιάς, and in Assyrian ''Kue''. Family Cilix was the brother of Cadmus, Phoenix and Europa. He was the father of The ...

Europa (consort Of Zeus)
In Greek mythology, Europa (; grc, Εὐρώπη, ''Eurṓpē'', ) was a Phoenician princess of Argive Greek origin, and the mother of King Minos of Crete. The continent of Europe may be named after her. The story of her abduction by Zeus in the form of a bull was a Cretan story; as classicist Károly Kerényi points out, "most of the love-stories concerning Zeus originated from more ancient tales describing his marriages with goddesses. This can especially be said of the story of Europa." Europa's earliest literary reference is in the ''Iliad'', which is commonly dated to the 8th century BC. Another early reference to her is in a fragment of the Hesiodic ''Catalogue of Women'', discovered at Oxyrhynchus.Hesiodic papyrus fragment19 and 19A of the ''Catalogue of Women'', dating from the third century AD. The earliest vase-painting securely identifiable as Europa dates from the mid-7th century BC. Etymology Greek (''Eurṓpē'') contains the elements εὐρύς (''eurus''), ...
