With the bright stars Deneb and Vega, Altair (Arabic for “flying eagle”) forms the prominent asterism of the Summer Triangle. From a latitude including New York and Madrid, Vega is only below the horizon about seven hours a day, so it can be viewed any night of the year. Vega, also called Alpha Lyrae, brightest star in the northern constellation Lyra and fifth brightest in the night sky, with a visual magnitude of 0.03. It is the 5th brightest star in the night sky and, because Earth's pole wobbles over time, it will take Polaris's place as the North Star in 14,000 AD. This show is also notable for perhaps the only known portrayal of a house with a "drive-in" living room. Vega definition, a star of the first magnitude in the constellation Lyra. Vega is a classic class A (A0) white main sequence dwarf star, like the Sun quietly running off the nuclear fusion of hydrogen deep in its core, with a sort of average effective surface temperature of about 9500 degrees Kelvin. The equator of Vega is 19% bigger than its polar radius. It is not visible south of 51° S, so it cannot be seen at all from the southern part of South America or Antarctica. Further south, Vega is below the horizon more of the time and may be trickier to find. Although the star was estimated previously to have 2.3 to 3.1 times Sol's mass, a 2012 analysis now suggests around 2.15 Solar-masses (Ken Croswell, Science Now, December 3, 2012 and Monnier et al, 2012). Vega is the fifth-brightest star in the night sky and the second-brightest star in the northern celestial hemisphere (after Arcturus). The name Vega comes from Arabic, whereas the name Capella comes from Latin. The temperature will eventually reach 15,000,000 degrees Celsius and nuclear fusion happens in the cloud's core. Because of the star's orientation with respect to Earth, the bulge appears unusually pronounced. Corrections? Vega appears to be surrounded by a disk of dust. Vega is a nearby optical spectral type A0V star at about 25 lyrs. Vega: The North Star of the Past and the Future Locating Vega. Types of Stars. Photos of STAR VEGA (MMSI: 636019734) Browse and rate photos uploaded by our community. It is the 5th brightest star in the night sky and, because Earth's pole wobbles over time, it will take Polaris's place as the North Star in 14,000 AD. Star X is in luminosity class III while Star Y is in luminosity class V. Star X must be larger in radius than Star Y. T. Also known as Vegans, they were originated from Lyra so that they could colonise and dominate the dog star, Sirius. Vega was one of the stars used to define the magnitude scale, so it has an apparent magnitude around 0 (+0.026). Vega is at the top of the triangle, with Deneb below it and to the left and Altair below both stars and to the right. Life of a Star: The life cycle of a star begins as a dust cloud. Procyon B Facts. - Vega is the fifth-brightest star in the night sky, and it is the brightest star in Lyra's northern constellation. ... T/F: Two stars have the same spectral type. Vega will become yet again the northern pole star, but this will happen in the year 13.727. Vega is surrounded by a disk of circumstellar dust that may be similar to the solar system’s Kuiper Belt. Updates? Star type. The star has a visual magnitude of 0.77. Right now, the North Star is Polaris, but Vega was the northern pole star around 12,000 BC and will the pole star again about the 13,727. Along with their brightness (apparent magnitude), the spectral class of a star can tell astronomers a lot about it. In another 500 million years or so, Vega will become a class-M red giant, after which it will lose most of its mass and become a white dwarf. It is also one of the Sun’s closer neighbours, at a distance of about 25 light-years. This condenses and forms a protostar before igniting to become a main sequence star. While Vega fuses hydrogen, most of the energy at its core comes from the carbon-nitrogen-oxygen (CNO cycle) in which protons combine to form helium with intermediate nuclei of the elements carbon, nitrogen, and oxygen, This process is less efficient than the Sun's proton-proton chain reaction fusion and requires a high temperature of about 15 million Kelvin. Of a beautiful white color, it belongs to the spectral type A0 and is on the main sequence as the Sun… The surface temperature of the star Vega is 9,602 degrees Kelvin. Vega is also one of the first stars to have its distance estimated through parallax measurements. Vega Facts. If Vega was viewed from above one of its poles, it would appear round. Vega . Vega Star Notes - Vega is a blue main-sequence star of spectral type A0V. Articles from Britannica Encyclopedias for elementary and high school students. Vega synonyms, Vega pronunciation, Vega translation, English dictionary definition of Vega. Vega (Italian: Vettore Europeo di Generazione Avanzata, or French: Vecteur européen de génération avancée, or English: European Vector of Advanced Generation meaning "Advanced generation European carrier rocket"), is an expendable launch system in use by Arianespace jointly developed by the Italian Space Agency (ASI) and the European Space Agency (ESA).
