How does pegasus look like
When Perseus defeated Medusa, Pegasus and the warrior Chrysaor sprang from her neck, both of them offspring of Poseidon. When he was born, Pegasus flew away to Mount Helicon in Boeotia, where the Muses lived, and he befriended them. He created a spring that was named Hippocrene by striking the ground with his hoof.
Bellerophon found Pegasus and tamed him using a golden bridle given to him by the goddess Athena. Then he swooped down on the Chimaera from the sky and defeated the monster with his lance and arrows. After this and several other heroic deeds for King Iobates, Bellerophon let the successes get to his head. Riding Pegasus, he tried to fly to Olympus and join the gods. He fell off the horse and back to Earth. Pegasus did however make it to Olympus.
There, Zeus used the horse to carry his thunder and lightning, and eventually placed him among the constellations. The constellation Pegasus is depicted with only the top half of the horse, and it is nevertheless one of the largest constellations in the sky, seventh in size. The Great Square of Pegasus represents the main body of Pegasus. The name Delta Pegasi has long been retired and the star is now known only as Alpha Andromedae , or by its proper name, Alpheratz.
It has an apparent magnitude of 2. It is only the third brightest star in Pegasus. It has a radius almost five times that of the Sun. Beta Pegasi is the second brightest star in the constellation. It has the stellar classification M2. It is about times more luminous than the Sun.
Beta Pegasi has an apparent magnitude of 2. It is classified as a semi-regular variable star with a period of Its brightness ranges from magnitude 2.
The star is losing mass and as a result it has a shell of gas and dust that is expanding with a radius of about times that of the Sun. Algenib is a subgiant star of the spectral type B2 IV.
It has a visual magnitude of 2. It marks the lower left-hand corner of the Great Square of Pegasus. It has a radial pulsation period of 0. Algenib is almost nine times as massive as the Sun and has about five times the solar radius. It is times more luminous than the Sun. Epsilon Pegasi is the brightest star in Pegasus.
Enif belongs to the spectral class K2 Ib. This means that it is an orange supergiant. Epsilon Pegasi is classified as a LC type slow irregular variable. It varies from 0. The star is also notable for having a relatively high peculiar velocity true velocity of Zeta Pegasi is a main sequence star of the spectral type B8 V.
In the mythology of ancient Greece, Pegasus, whose name comes from pegai , the Greek word for waters or springs, was the war horse of Zeus, the ruler, protector, and father of both gods and humans. When Zeus went into battle, it was Pegasus who carried his arsenal of thunder and lighting. For his loyalty, Zeus rewarded Pegasus by making him a constellation in the sky. In another account of Pegasus, the horse was born from the blood of Medusa after she was slain by the hero Perseus.
The brightest star in the constellation is Epsilon Pegasi, which forms the nose, according to Jim Kaler , an astronomer and professor emeritus at the University of Illinois.
Another star in this constellation, 51 Pegasi b, is the first sun-like star known to have a planet orbiting around it. The planet is roughly 50 light-years away from Earth and is classified as a "hot Jupiter" — a planet that is Jupiter-size and orbits close to its parent star.
The visible light spectrum of 51 Pegasi b's atmosphere was observed in In that same year, the IAU announced that it would also call 51 Pegasi b by the name Dimidium , following a public vote.
Pegasus contains a Messier object , named M15, which is a cluster of stars that are about 34, light-years from Earth. M15 is one of the most densely packed clusters in the Milky Way galaxy. Pegasus , the winged horse in Greek Mythology, was involved in some of the most intriguing tales of the times.
Pegasus was represented as a goodhearted, gentle creature, somewhat naive but always eager to help. For his service and loyalty, Zeus honored him with a special immortality turning Pegasus into a constellation on the last day of his life.
