Stephan’s Quintet, as the name implies, is a group of five galaxies. Although Pegasus doesn't exactly look like a horse—more like a box with legs attached—its shape is so easily recognizable that it's hard to miss. The brighter component is a main sequence star belonging to the spectral class A8m. The star is also notable for having a relatively high peculiar velocity (true velocity) of 21.6 km/s.Zeta Pegasi is a main sequence star of the spectral type B8 V. It has an apparent magnitude of 3.414 and is about 204 light years distant from the Sun.

He fell off the horse and back to Earth.Pegasus did however make it to Olympus. The story of Pegasus begins with a battle between Perseus and Medusa. After this and several other heroic deeds for King Iobates, Bellerophon let the successes get to his head. This is a prominent asterism that is created by three bright stars in Pegasus and Alpha Andromedae. It is also older than the Sun, with an estimated age between 6.1 and 8.1 billion years.The exoplanet, 51 Pegasi b, was discovered on October 6, 1995.

The two stars in the system have an orbital period of 21.7 days. It is classified as a Seyfert galaxy undergoing star forming activity in the core and outer spiral arms.In this NASA & ESA Hubble Space Telescope image of NGC 7479 — created from observations at visible and near-infrared wavelengths — the tightly wound arms of the spiral galaxy create an inverted ‘S’, as they spin in an anticlockwise direction.
part of the easily recognisable asterism the Square of Pegasus, which comprises NGC 7753 is a barred spiral galaxy and NGC 7753 is its satellite galaxy, a barred lenticular galaxy that appears to be attached to one of NGC 7753’s arms.The galaxies have visual magnitudes of 15.0 and 12.8 and are approximately 272 million light years distant from the solar system.A supernova, SN 2006A, was observed in NGC 7753 in January 2006.Necessary cookies are absolutely essential for the website to function properly. The other four galaxies in the group form a physical association, the Hickson Compact Group 92, and will eventually merge.Stephan’s Quintet–A Galaxy Collision in Action Stephan’s Quintet, a compact group of galaxies discovered about 130 years ago and located about 280 million light years from Earth, provides a rare opportunity to observe a galaxy group in the process of evolving from an X-ray faint system dominated by spiral galaxies to a more developed system dominated by elliptical galaxies and bright X-ray emission. Athena turned Medusa’s hair into snakes and made her face so ugly that anyone who looked at her immediately turned to stone.Perseus was sent to kill Medusa by King Polydectes of Seriphus, who was the brother of Dictys, the man who took Perseus and his mother Danaë in and raised Perseus as his own son. The neighboring constellations are Andromeda, Aquarius, Cygnus, Delphinus, Equuleus, Lacerta, Pisces and Vulpecula. Pegasus is visible in both the Northern and Southern hemispheres.
The quasar is about 8 billion light years distant from the Sun, while Huchra’s lens lies only 400 million light years away.The exact location of the quasar is at 22h40m30.3 (right ascension), +3°21’30.3” (declination).NGC 7814 is a spiral galaxy in Pegasus seen edge-on. It has two visual companions, a magnitude 11.6 star 68 arc seconds away and an 11th magnitude star 177 arc seconds away.The star’s traditional name, Homam, means “the lucky star of the high minded” or “man of high spirit.”Eta Pegasi is a double star approximately 167 light years distant from the solar system. In the Northern Hemisphere, the constellation is high in the sky starting near the end of summer and continuing through autumn. It has a radius almost ten times solar, but is only slightly more massive than the Sun, about 2.7 times.The star’s traditional name, Sadalbari, comes from the Arabic phrase for “luck star of the splendid one.”51 Pegasi is a main sequence star similar to the Sun, approximately 50.9 light years distant from Earth. It is 1.2’x1.2′ in size and has a visual magnitude of 13.9.The galaxy is notable because a Type Ia supernova, SN 2007B, was observed in it in 2007.NGC 7742 is an unbarred spiral galaxy in Pegasus, seen face-on. Key Data.

Its brightest stars form With our standard star naming offer, you can name a real star, which will be visible from any place on earth throughout the year. In Greek mythology this constellation was identified with the winged horse Pegasus that was ridden by the Greek heroes Perseus and Bellerophon. He created a spring that was named Hippocrene by striking the ground with his hoof.

The brightest galaxy in the group is NGC 7320, which is only 40 million light years distant. It is the nearest supernova progenitor candidate known, and will eventually explode as a Type Ia supernova once the brighter star in the system evolves into a red giant and grows a radius that allows the white dwarf to accrete matter from its expanded gaseous envelope.Messier 15 is a globular cluster, about 18 arc minutes in size.
