Eridanos (mythology)
The river Eridanos or Eridanus (; grc, Ἠριδανός) is a river in northern Europe mentioned in Greek mythology and historiography Historiography is the study of the methods of historians in developing history as an academic discipline, and by extension is any body of historical work on a particular subject. The historiography of a specific topic covers how historians ha .... Mythical stream Hesiod, in the ''Theogony,'' calls it "deep-eddying Eridanos" in his list of rivers, the offspring of the Titans Tethys (mythology), Tethys and her brother-husband Oceanus. He was called the king of the rivers. Herodotus suspects the word ''Eridanos'' to be essentially Greek in character, and notably forged by some unknown poet, and expresses his disbelief in the whole concept—passed on to him by others, themselves not eye witnesses—of such a river flowing into a northern sea, surrounding Europe, where the mythical Amber#History and names, Amber and Cassiterides#Ancient ge ...

Eta Eridani
Eta Eridani (η Eridani, abbreviated Eta Eri, η Eri), officially named Azha (with a silent 'h', possibly ), is a giant star in the constellation of Eridanus. Based on parallax measurements taken during the Hipparcos mission, it is approximately 137 light-years from the Sun. Nomenclature ''η Eridani'' ( Latinised to ''Eta Eridani'') is the star's Bayer designation. It bore the traditional name ''Azha'', from the old Arab asterism نَعَام أُدْحِيّ ''udḥiyy al-naʽām'' "the ostrich nest" (or "hatching place"), which included Eta Eridani. The first word, ادحى ''udḥiyy'', was miscopied as ازحى (readable as ''azḥā'') in medieval manuscripts. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalogue and standardize proper names for stars. The WGSN approved the name ''Azha'' for this star on 12 September 2016 and it is now so included in the List of IAU-approved Star Names. In Chinese, (), ...

Éridan-class Minehunter
The Tripartite class is a class of minehunters developed from an agreement between the navies of Belgium, France and the Netherlands. A total of 35 ships were constructed for the three navies. The class was constructed in the 1980s–1990s in all three countries, using a mix of minehunting, electrical and propulsion systems from the three member nations. In France, where they are known as the ''Éridan'' class they are primarily used as minehunters, but have been used for minesweeping and ammunition transport in Belgium and the Netherlands, where the Tripartites are known as the ''Alkmaar'' class. In 1992, the Pakistan Navy acquired three vessels from France, one that was already built, one to be built in France and one built in France and Pakistan. Known as the ''Munsif'' class, all three are still in service. The Indonesian Navy acquired two minehunters in the 1990s from the Dutch to a modified design. Known as the ''Pulau Rengat'' class, the two ships are still in service. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Éridan (rocket)
The Éridan is a two-stage French sounding rocket, which resulted from the use of the Stromboli engine of the Dragon and/or Dauphin as first and second stage. It belonged thereby to a family of solid-propellant rockets from the Belier (rocket), the Centaure (rocket) Centaure was a two-stage French sounding rocket consisting of a Belier (rocket) starting stage and a Venus upper stage. It was operated by CNES between 1961 and 1986. The Centaure has been built in a number of 230 and has been launched from th ..., to the Dragon, the Dauphin and the Eridan. As the most powerful version of this series it could lift payloads from 100 to 420 kg to heights of 200 to a maximum of 460 km. Its climbing time is between 230 and 350 seconds.Les débuts de la recherche spatiale française 2846082154 IFHE,, Institut français d'histoire de l'espace - 2007 Intéressés, ils demandèrent au CNES d'envisager sérieusement un projet d'astronomie spatiale d'envergure qui serait réali ...

Gamma Eridani
Gamma Eridani (γ Eridani, abbreviated Gamma Eri, γ Eri), formally named Zaurak , is a variable star in the constellation of Eridanus. It is visible to the naked eye with an apparent visual magnitude that varies around 2.9, and lies at a distance of about 203 light years from the Sun, as determined by the Hipparcos astrometry satellite. Description Gamma Eridani has been defined as a standard star for the spectral class M0III-IIIb. It is a red giant on the asymptotic giant branch, fusing hydrogen and helium in separate shells outside its core. Observations published in 1960 showed it to vary in brightness by a few hundredths of a magnitude. In 1977, it was officially listed as a variable star in the General Catalogue of Variable Stars although the class of variable is uncertain. Nomenclature ''Gamma Eridani'' is the star's Bayer designation. It has the traditional name ''Zaurak'', alternatively spelled Zaurac, which is Arabic for 'boat'. In 2016, the In ...

Delta Eridani
Delta Eridani, which is Latinized from δ Eridani, is a star in the equatorial constellation of Eridanus. The star is visible to the naked eye and has been observed to vary in slightly brightness between magnitudes 3.51 and 3.56, although subsequent observations did not bear this out. It is relatively near to the Sun, with a distance of about 29.5 light years as determined from parallax. The star is drifting closer with a radial velocity of −6 km/s. Delta Eridani is sometimes called Rana: ''Rana'' means "the frog" in Latin, but derivation of this name is uncertain. The name was approved by the International Astronomic Union on 4 April 2022. Structure The stellar classification of this star is K0 IV, matching a subgiant star that has exhausted its core hydrogen. This has caused the star to expand and become cooler than a comparable main sequence star. Stellar modelling indicates it is near the end of the subgiant stage and about to transition in ...

Po River
The Po ( , ; la, Padus or ; Ligurian language (ancient), Ancient Ligurian: or ) is the longest river in Italy. It flows eastward across northern Italy starting from the Cottian Alps. The river's length is either or , if the Maira (river), Maira, a right bank tributary, is included. The headwaters of the Po are a Spring (hydrology), spring seeping from a stony hillside at Pian del Re, a flat place at the head of the Val Po under the northwest face of Monviso. The Po then extends along the 45th parallel north before ending at a delta projecting into the Adriatic Sea near Venice. It is characterized by its large Discharge (hydrology), discharge (several List of rivers by length, rivers over 1,000 km have a discharge inferior or equal to the Po). It is, with the Rhône and Nile, one of the three Mediterranean rivers with the largest water discharge. As a result of its characteristics, the river is subject to heavy flooding.

Eridanus II
The Eridanus II Dwarf is a low-surface brightness dwarf galaxy in the constellation Eridanus. Eridanus II was independently discovered by two groups in 2015, using data from the Dark Energy Survey ( Bechtol et al., 2015; Koposov et al. 2015). This galaxy is probably a distant satellite of the Milky Way. Li et al., 2016. Eridanus II contains a centrally located globular cluster; and is the smallest, least luminous galaxy known to contain a globular cluster. Crnojević et al., 2016. Eridanus II is significant, in a general sense, because the widely accepted Lambda CDM cosmology predicts the existence of many more dwarf galaxies than have yet been observed. The search for just such bodies was one of the motivations for the ongoing Dark Energy Survey observations. Eridanus II has special significance because of its apparently stable globular cluster. The stability of this cluster, near the center of such a small, diffuse, galaxy places constraints on the nature of dark matter. ...
