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.

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.

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.
