constellation of perseus and andromeda

The Perseid meteorite shower, the most impressive in the sky, does not actually come from the constellation Perseus but is the rubble left behind from the Comet Swift-Tuttle, the supposed parent of the Perseids. Menkhib has around 2,600% of our Sun’s mass, 1,400% of its radius, and it is 6.05 times hotter than our Sun, having temperatures of around 35,000 K. It is also a fast-spinning star, with a rotational velocity recorded at 220 km / 136.7 mi per second. Misam is also similar in age to our Sun, being 4.58 billion years old. In Neo-Assyrian Babylonia (911 to 605 BC), the constellation of Perseus was known as the Old Man constellation – SU.GI. 48 Persei has around 750% of our Sun’s mass, and it is 600 times brighter than our Sun. [15], Algol (from the Arabic رأس الغول Ra's al-Ghul, which means The Demon's Head), also known by its Bayer designation Beta Persei, is the best-known star in Perseus. [51], Named Gorgonea Tertia, Rho Persei varies in brightness like Algol, but is a pulsating rather than eclipsing star. Some star atlases during the early 19th century also depicted Perseus holding the disembodied head of Medusa,[3] whose asterism was named together as Perseus et Caput Medusae;[4] however, this never came into popular usage. NGC 1058 is a type 2 Seyfert galaxy in the NGC 1023 Group of galaxies. [68][69] Both lie more than 7,000 light-years from Earth and are several hundred light-years apart. The Perseus constellation is in the center of a lot of famous constellations such as Taurus and Aries in the south. Andromeda is a northern constellation located directly south of Cassiopeia between Pegasus and Perseus. It is named after Andromeda, the daughter of Queen Cassiopeia and wife of the Greek hero Perseus. Algol, designated as Beta Persei, and colloquially known as the Demon Star, is a multiple star system located in Perseus. AX Persei is another binary star, the primary component is a red giant in an advanced phase of stellar evolution, which is transferring material onto an accretion disc around a smaller star. Positioned north of the ecliptic plane, the constellation of Perseus was one of the original 48 constellations listed by Ptolemy, and endures as one of the 88 modern constellations… Currently, around 7 stars in Perseus have been confirmed to host exoplanets. The primary star, Delta Persei A, has around 700% of our Sun’s mass, 1,050% of its radius ( thus it is 21 times bigger than our Sun), and it is almost three times hotter than our Sun, with temperatures reaching 14,890 K.

Perseus is a constellation in the northern sky, being named after the Greek mythological hero Perseus. Its helium has been fused into heavier elements and its core is composed of carbon and oxygen. You can see the Auriga constellation in the east, Cassiopeia in the north, and the Andromeda Galaxy to the west. The two are Trumpler class I 3 r clusters, though NGC 869 is a Shapley class f and NGC 884 is a Shapley class e cluster. It is visible to the naked eye under the right conditions. The star that exploded was 1,560 light-years away from us. The constellation of Perseus is one of the oldest Greek constellations, first listed by Ptolemy, in his 2nd century Almagest. Perseus slew Medusa in her sleep, and Pegasus and Chrysaor appeared from her body. It has around 1,350% of our Sun’s mass, 766% of its radius, and it is 28,330 times brighter than our Sun. Located north of the celestial equator, this constellation is part of the family of Perseus, Cassiopeia, and Cepheus. Discovered on 21 February 1901 by Scottish amateur astronomer Thomas David Anderson, it peaked at magnitude 0.2—almost as bright as Capella and Vega. This star is also three times hotter than our Sun, having temperatures of around, 16,143 K, and it is also a fast-spinning star, with a rotational velocity recorded at 120 km / 74.5 mi per second. [18] The brightest component is a blue-white main-sequence star of spectral type B8V,[19] which is 3.5 times as massive and 180 times as luminous as the Sun. Incorporating stars from the northern part of the constellation, it contained Mu, Delta, Psi, Alpha, Gamma and Eta Persei. [18] The secondary component is an orange subgiant star of type K0IV that has begun cooling and expanding to 3.5 times the radius of the Sun,[20] and has 4.5 times the luminosity and 80% of its mass. It has an apparent magnitude of 2.12, which sometimes drops to magnitude 3.4 every 2.86 days. [35] With an apparent magnitude of 6.72, it is too dim to be seen with the naked eye even in perfectly dark conditions. [12] Algol may have been named Matohi by the Māori people, but the evidence for this identification is disputed. It has a combined apparent magnitude of +2.88, making it visible to the naked eye, and one of the brightest stars in Perseus. Currently, around 7 stars in Perseus have been confirmed to host exoplanets. Perseus is commonly depicted as holding the head of Medusa in one hand, and a jeweled dagger in the other.

Messier 34, also designated as NGC 1039, is an open cluster located at around 1,500 light-years away from us. This cluster has many blue B-type stars, with its brightest member being the white-yellow supergiant Mirfak / Alpha Persei. There are only two Messier Objects located in the constellation of Perseus, the open cluster Messier 34, and the planetary nebula Messier 76. IC 348 is a somewhat young open cluster that is still contained within the nebula from which its stars formed. This star is located amid a cluster of stars, the Alpha Persei Cluster, and one exoplanet is speculated to orbit Mirfak, which would have at least 660% of Jupiter’s mass. Three stars can be distinguished in the Algol star system, and they are designated as Beta Persei Aa1, Aa2, and Ab. In Greek mythology, Perseus was the son of Danaë, who was sent by King Polydectes to bring the head of Medusa the Gorgon—whose visage caused all who gazed upon her to turn to stone. Cassiopeia and Cepheus accepted. Ethiopia’s role in the story of the Almighty God; Maaza Mengiste’s “The … The meteors appear to flow from the constellation Perseus (hence the name Perseids) in mid-August.

At an estimated distance of 1,475 light-years from Earth, the system is now thought to lie too far from the center of the Zeta Persei group to belong to it. 30 Persei is a binary star located at around 730 light-years away from us. The primary star is a member of the Perseus OB3 association, a group of stars that share the same motion through space, and origin. [70] The clusters are both distinct from the surrounding star field and are clearly concentrated at their centers. It has an apparent magnitude of 12.6, being the brightest member of the Perseus Cluster of galaxies. Perseus killed the monster and freed Andromeda. It is in the middle of "The Sea" because it belongs in an area with a set of water-associated constellations like Aquarius, Eridanus, Pisces and Piscis Austrinus. Gorgonea Tertia, designated as Rho Persei, is an M-type bright giant star, and it is the third member of the quartet called the Gorgonea, in reference to the Gorgons from the legend of Perseus. Psi Persei is a B-type main-sequence star that has around 470% of our Sun’s radius, thus it is more than five times bigger. The secondary has a similar spectral type to O-type subdwarfs. Tiānchuán (天船), the Celestial Boat, was the third paranatellon (A star or constellation which rises at the same time as another star or object[9]) of the third house of the White Tiger of the West, representing the boats that Chinese people were reminded to build in case of a catastrophic flood season. Area: (79th) Symbolism: The chameleon. The monster had been sent by Poseidon as a punishment for Queen Cassiopeia’s boasting that her daughter was more beautiful than … AG Persei is another Algol variable in Perseus, whose primary component is a B-type main sequence star with an apparent magnitude of 6.69. It is one of the very rare DY Persei Class of variables, that pulsate like red variables but also fade from sight like R Coronae Borealis variables. The brightest stars in the constellation — Alpheratz, Mirach and Almach — form a chain between the Great Square of Pegasus and the constellation Perseus. The Perseids are a prominent annual meteor shower that occurs from mid-July, while peaking between 9 and 14 August each year. 10 Best Places To Visit in Ethiopia.
