Stars Eri

Stars Eri – The constellation of the Creek is the second largest in terms of length (after the Blue Snake – Brave) and the sixth constellation in terms of size. This group of faint stars has been known as a river (usually a reference to the Euphrates or Nile River) since ancient times. The constellation of the creek first turns to the west and the constellation of Quotes, then to the south and between the constellations of the furnace and the chisel from the constellations of the southern hemisphere. In classical times, the southernmost point of this constellation reached the cruel star or Theta Creek. But later its limit was extended from the first magnitude to the end star of the creek, the alpha of the face of the creek, which is a star. The time of reaching the meridian is January 6, and its area is 1138 square degrees. The river is one of the longest forms of the sky. It is a stream that is located a few degrees northwest of Rijal al-Jabbar. The first magnitude can not be seen in mid-latitudes. This star is only 33 degrees to the celestial south pole and never rises for observers before 33 degrees north latitude.

The star alpha or the end of the river is derived from the Arabic word at the bottom of the river. This star can only be seen from latitudes below 30 degrees north. Its spectrum is B3 V, its magnitude is 0.5 and it is 69 light-years away from us.

Deep-sky objects – Stars Eri
IC2118 is a very large reflecting nebula (about 40 × 140 arc minutes) located just below the beta star 2.5 degrees northwest of the star Ori beta, which is likely to be illuminated by the brightness of that bright star. There are several dozen dimly lit galaxies (less than 10) in the constellation Pisces.

The star of the end of the river may be the same Sedus in Avesta and Pahlavi and mythological texts. And the star of Soheil is the counterpart of Opam Napat. On the contrary, it is possible that Akhar al-Nahr is Opam Napat and Soheil Sedvis. The three stars Sedvis, Opam Napat and Tishter together play an important role in rainfall, and all three are natural. Open Napat is one of the three gods who are called Ahura in Vedic mythology (pre-Avestan). The star of the end of the creek, the brightest star in the body of the creek, is the most elliptical star known. Akhar al-Nahr has a very fast period and it takes less than 3 days to go around it once. It is because of this rapid period that it has become more prominent in the equator and its appearance has become extremely flat. The equatorial protrusion of the equator is better known than any other star. Its tropical diameter is more than 50% longer than its polar diameter. } (Illustrated Encyclopedia of the Secrets of the Stars of Sayan, p. 160)

Constellation Taurus

Because the constellation of bright stars in the constellation of Jabbar is more than any other constellation, it has long been considered and admired by various civilizations and due to its location on the celestial equator, it has been visible to the inhabitants of both hemispheres (north and south). In ancient astronomy, the constellations of the southern hemisphere were considered the sky. In Babylonian and Indian mythology, this constellation was thought to be the cause of winter storms. Polybius (2nd century BC) blamed the naval voyage of the Roman armies at the dawn of Jabbar for their defeat in the First Punic (Carthage) war. Later in medieval Europe, algebra was considered a calendar symbol, as its rising at midnight marked the beginning of the grape picking season.

Letters of the constellation Orion
One of the names of this constellation in Greek was Arion, which means warrior, which is probably derived from the Akkadian word Arvana meaning heavenly light, and may have later found its way into Greek mythology and astronomy through Mesopotamian civilizations. Even today, Jabbar is known in European languages ​​as Orion. In Greek mythology, Orion was the son of Neptune and a powerful hunter who claimed to be superior to all creatures. According to one version, Orion was accidentally killed by Diana (the goddess of hunting) and was killed by a scorpion bite, according to another version. However, in the sky, the constellations of the hunter and the scorpion were placed at opposite points so that the scorpion would not bite the hunter again. Two dogs (the constellations of the Big Dipper and the Little Dipper) accompany the hunter, and a rabbit (the constellation of the Ornab) is under his feet. In the astronomy of the Islamic period, the constellation of Kalb-e-Akbar is also mentioned as Kalb-e-Jabbar.
