Mythology and history

	The Pegaso or Pegasus in Greek mythology was the winged horse, son of Poseidón, God of the sea, and gorgona Medusa. The Pegaso was born of the neck of Medusa after being overcome and being died by the Perseo hero. Shortly after his birth, the magician corcel struck with a kick the ground of the Helicón mount and in the act he began to flow a spring, later consecrated to the Musas and that, according to is created, is the source of the poetic inspiration. All in vain tried to capture and to tame the horse, and to obtain it became the obsession of Belerofonte, prince of Corinto. Following the advice of a fortune teller, Belerofonte spent one night in the temple of the Athenian goddess. While it slept, it appeared to him the goddess with a bridle of gold and it said to him that this one would allow him to capture the Pegaso. When it woke up, it found the gold bridle next to him, and with her could easily capture and tame the winged horse.
As of that moment, the Pegaso became a great aid for the hero and it accompanied in his adventures against the amazons and the Chimera. Belerofonte, nevertheless, was victim of its own pride. When it managed to fly until the top of the Mount Olympus mount to meet with the Gods, the prudent horse demolished and left it to Belerofonte quarter-railings without course, heartbroken, rejected by the inmortales. The Pegaso found refuge in the Olympic stables and Zeus ordered to him that he took to the thunderclap and the ray to him, the symbols of his power.

Characteristics

          Pegasus is a precious and enormous square boreal constellation of more of 900º located between the parallels 30º and 10º of visible North latitude for more than seven months in the North hemisphere from the months of Julio to January; however, in the South hemisphere it culminates to low height during the months of February, March and April. The one of the most evident characteristics when observing constellation is that it has quadrilateral form whose asterism already very popular, is formed peculiarly by four stars of the second magnitude but with the particularitity of which the one that is in the western and  superior end it belongs to the neighboring constellation of Andromeda, the rest, logically comprises of the constellation of Pegasus. It turns out fascinating to observe the constellation in nights very closed and to be able to get to at first detect with the eyes some weak stars within the asterism.

            The constellation of Pegasus is enough free of the stellar clouds and dust that project in the Milky Route for that reason we pruned to observe globular clusters and galaxies with certain facility. it's 40º to the south of the equator of our galaxy, compares her, and to the north of the ecliptic, also it compares limiting the south with the zodiacal constellations of aquarium and fish (Aquarius and Piscis).

        Pegasus limits the north with the constellations of Andromeda and Lacerta (the lizard), to the east with Cygnus, Vulpecula (the vixen), Equuelus (the pony) and Delphinus; to the south with the zodiacal constellations of Aquarius and Piscis and to the west with Piscis and the wonderful Andromeda.

        The constellation of Pegasus I located the 4 to it of Julio of 1982 at the age of 14 years from the locality of Cán Picafort, Majorca, Spain.

Main stars        Alpha, a; denominated Markab, of magnitude 2.49 and white color, one is in the Southeastern end of the quadrilateral. it's of us 140 years Earth light and is a giant 150 times more luminous than our Sun.       Beta, b; denominated Scheat, or "forcebody" of magnitude 2.47, one is in the Eastern North end of the quadrilateral, it's 200 years Earth light and one is a red giant 350 times more luminous than the Sun similar to Betelgeuse in brightness variations.     Gamma, g; located to the southwest of the quadrilateral, its magnitude is of 2.84, is a blue giant 640 times more luminous than the Sun, denominated Algenib, it's 330 years light of us.     Delta, d; one is the Eastern North star of the quadrilateral that belongs to the constellation of denominated a Andromedae.     Epsilon, e; of magnitude 2.39, it is the star most shining of the constellation of Pegasus and peculiarly it is not located in the famous quadrilateral but in the Eastern end of the constellation already near Equuleus, it comes to be the snout of the winged horse. Denominated Enif of the Arab nose, it is an orange supergiant 4000 times more shining than the Sun that it's 670 years light of us. Other objects           M 15; wonderful and impressive globular cluster of magnitude 6,4; it has an angular diameter of 7' of arc and it's of us 30,000 years light; it has a diameter of 150 years light.
