Zodiac Symbol
The zodiac is a belt-shaped region of the sky that extends approximately 8° north or south (as measured in celestial latitude) of the ecliptic, the Sun path, apparent path of the Sun across the celestial sphere over the course of the year. The paths of the Moon and visible planets are within the belt of the zodiac. In Western astrology, and formerly astronomy, the zodiac is divided into astrological sign, twelve signs, each occupying 30° of celestial longitude and roughly corresponding to the following star constellations: Aries (astrology), Aries, Taurus (astrology), Taurus, Gemini (astrology), Gemini, Cancer (astrology), Cancer, Leo (astrology), Leo, Virgo (astrology), Virgo, Libra (astrology), Libra, Scorpio (astrology), Scorpio, Sagittarius (astrology), Sagittarius, Capricorn (astrology), Capricorn, Aquarius (astrology), Aquarius, and Pisces (astrology), Pisces. These astrological signs form a celestial coordinate system, or more specifically an ecliptic coordinate sys ...

Ecliptic Path
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 ...

Leo (astrology)
Leo () (Ancient Greek, Greek: , ''Leōn''), Latin for Lion, is the fifth Astrological sign, sign of the zodiac. It corresponds to the Leo (constellation), constellation Leo and comes after Cancer (astrology), Cancer and before Virgo (astrology), Virgo. The traditional Western zodiac associates Leo with the period between about July 23 and August 22, and the sign spans the 120th to 150th degree of celestial longitude. Leo is associated with Fire sign, fire, accompanied by Aries and Sagittarius, and its modality is fixed sign, fixed. The constellation Leo is associated with the mythological Nemean lion. The lion is a very important and prominent symbol in Greek mythology. History Egyptians worshipped the constellation, which they referred to as "Knem", because it was present during the flooding of the Nile River. This event signified plentiful harvests for the upcoming year, and the people interpreted it as a gift from the earth. Ruler of Egypt, Tutankhamun, Tutankhamun's gold ...

Latinisation Of Names
Latinisation (or Latinization) of names, also known as onomastic Latinisation, is the practice of rendering a ''non''-Latin name in a Latin style. It is commonly found with historical proper names, including personal names and toponyms, and in the standard binomial nomenclature of the life sciences. It goes further than romanisation, which is the transliteration of a word to the Latin alphabet from another script (e.g. Cyrillic). For authors writing in Latin, this change allows the name to function grammatically in a sentence through declension. In a scientific context, the main purpose of Latinisation may be to produce a name which is internationally consistent. Latinisation may be carried out by: * transforming the name into Latin sounds (e.g. for ), or * adding Latinate suffixes to the end of a name (e.g. for '' Meibom),'' or * translating a name with a specific meaning into Latin (e.g. for Italian ; both mean 'hunter'), or * choosing a new name based on some attribut ...

Equinox (celestial Coordinates)
In astronomy, an equinox is either of two places on the celestial sphere at which the ecliptic intersects the celestial equator. Although there are two such intersections, the equinox associated with the Sun's ascending node is used as the conventional origin of celestial coordinate systems and referred to simply as "the equinox". In contrast to the common usage of spring/vernal and autumnal equinoxes, the celestial coordinate system equinox is a direction in space rather than a moment in time. In a cycle of about 25,800 years, the equinox moves westward with respect to the celestial sphere because of perturbing forces; therefore, in order to define a coordinate system, it is necessary to specify the date for which the equinox is chosen. This date should not be confused with the epoch. Astronomical objects show real movements such as orbital and proper motions, and the epoch defines the date for which the position of an object applies. Therefore, a complete specification of ...

Position Of The Sun
The position of the Sun in the sky is a function of both the time and the geographic location of observation on Earth's surface. As Earth orbits the Sun over the course of a year, the Sun appears to move with respect to the fixed stars on the celestial sphere, along a circular path called the ecliptic. Earth's rotation about its axis causes diurnal motion, so that the Sun appears to move across the sky in a Sun path that depends on the observer's geographic latitude. The time when the Sun transits the observer's meridian depends on the geographic longitude. To find the Sun's position for a given location at a given time, one may therefore proceed in three steps as follows: # calculate the Sun's position in the ecliptic coordinate system, # convert to the equatorial coordinate system, and # convert to the horizontal coordinate system, for the observer's local time and location. This is the coordinate system normally used to calculate the position of the Sun in terms of solar zen ...

Ecliptic Coordinate System
The ecliptic coordinate system is a celestial coordinate system commonly used for representing the apparent positions, orbits, and pole orientations of Solar System objects. Because most planets (except Mercury) and many small Solar System bodies have orbits with only slight inclinations to the ecliptic, using it as the fundamental plane is convenient. The system's origin can be the center of either the Sun or Earth, its primary direction is towards the vernal (March) equinox, and it has a right-hand convention. It may be implemented in spherical or rectangular coordinates. Primary direction The celestial equator and the ecliptic are slowly moving due to perturbing forces on the Earth, therefore the orientation of the primary direction, their intersection at the Northern Hemisphere vernal equinox, is not quite fixed. A slow motion of Earth's axis, precession, causes a slow, continuous turning of the coordinate system westward about the poles of the ecliptic, completi ...

Celestial Coordinate System
Astronomical coordinate systems are organized arrangements for specifying positions of satellites, planets, stars, galaxies, and other celestial objects relative to physical reference points available to a situated observer (e.g. the true horizon and north cardinal direction to an observer situated on the Earth's surface). Coordinate systems in astronomy can specify an object's position in three-dimensional space or plot merely its direction on a celestial sphere, if the object's distance is unknown or trivial. Spherical coordinates, projected on the celestial sphere, are analogous to the geographic coordinate system used on the surface of Earth. These differ in their choice of fundamental plane, which divides the celestial sphere into two equal hemispheres along a great circle. Rectangular coordinates, in appropriate units, have the same fundamental () plane and primary (-axis) direction, such as a rotation axis. Each coordinate system is named after its choice of fundamental ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Constellations
A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object. The origins of the earliest constellations likely go back to prehistory. People used them to relate stories of their beliefs, experiences, creation, or mythology. Different cultures and countries adopted their own constellations, some of which lasted into the early 20th century before today's constellations were internationally recognized. The recognition of constellations has changed significantly over time. Many changed in size or shape. Some became popular, only to drop into obscurity. Some were limited to a single culture or nation. The 48 traditional Western constellations are Greek. They are given in Aratus' work ''Phenomena'' and Ptolemy's '' Almagest'', though their origin probably predates these works by several centuries. Constellations in the far southern sky were adde ...

Pisces (astrology)
Pisces () (; grc, Ἰχθύες ''Ikhthyes'') is the twelfth and final astrological sign in the zodiac. It is a negative, mutable sign. It spans 330° to 360° of celestial longitude. Under the tropical zodiac, the sun transits this area between February 19 and March 20. In classical interpretations, the symbol of the fish is derived from the ichthyocentaurs, who aided Aphrodite when she was born from the sea. According to some tropical astrologers, the current astrological age is the Age of Pisces,Nicholas Campion, (1988) ''The Book of World Horoscopes'' Aquarian Press, Wellingborough while others maintain that currently it is the Age of Aquarius. Background While the astrological sign Pisces per definition runs from ecliptic longitude 330° to 0°, this position is now mostly covered by the constellation of Aquarius due to the precession from when the constellation and the sign coincided. Today, the First Point of Aries, or the vernal equinox, is in the Pisces conste ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Aquarius (astrology)
Aquarius () is the eleventh astrological sign in the zodiac, originating from the Aquarius (constellation), constellation Aquarius. Under the tropical zodiac, the Sun is in the Aquarius sign between about January 20 and about February 18. Myth The water carrier represented by the zodiacal constellation Aquarius is Ganymede (mythology), Ganymede, a beautiful Phrygian youth. Ganymede was the son of Tros, king of Troy (according to Lucian, he was also the son of Dardanus). While tending to his father's flocks on Mount Ida, Ganymede was spotted by Zeus. The king of gods fell in love with him and flew down to the mountain in the form of a large bird, whisking Ganymede away to the heavens. Ever since, the boy has served as cupbearer to the gods. Ovid has Orpheus sing the tale. Constellation Aquarius is a winter constellation in the northern hemisphere, found near Pisces and Cetus. It is especially notable as the radiant for four meteor showers, the largest of which is the Souther ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Capricorn (astrology)
Capricorn () is the tenth astrological sign in the zodiac out of twelve total zodiac signs, originating from the constellation of Capricornus, the goat. It spans the 270–300th degree of the zodiac, corresponding to celestial longitude. Under the tropical zodiac, the sun transits this area from about December 22 to January 19. In astrology, Capricorn is considered an earth sign, negative sign, and one of the four cardinal signs. Capricorn is said to be ruled by the planet Saturn. There appears to be a connection between traditional characterizations of Capricorn as a sea goat and the Sumerian god of wisdom and waters, who also had the head and upper body of a goat and the lower body and tail of a fish. Later known as ''Ea'' in Akkadian and Babylonian mythology, Enki was the god of intelligence (''gestú'', literally "ear"), creation, crafts; magic; water, seawater and lake water (''a, aba, ab''). Cultural significance In India, the zodiac sign of Capricorn is celebrat ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sagittarius (astrology)
Sagittarius () (Greek: Τοξότης ''Toxótēs'') is the ninth astrological sign, which is associated with the constellation Sagittarius and spans 240–270th degrees of the zodiac. Under the tropical zodiac, the sun transits this sign between approximately November 22 and December 21. Greek mythology associates Sagittarius with the centaur Chiron, who mentored Achilles, a Greek hero of the Trojan War, in archery. Sagittarius, the half human and half horse, is the centaur of mythology, the learned healer whose higher intelligence forms a bridge between Earth and Heaven. Also known as the Archer, Sagittarius is represented by the symbol of a bow and arrow. Astrology Along with Aries and Leo, Sagittarius is a part of the Fire Trigon as well as the last of the reproductive trinity. It also follows Gemini and Virgo as third of the mutable signs, which are the signs that feature changeable quality. When Sagittarius is depicted as an archer, then he is classified as human but ...
