With an apparent magnitude of 0.76, it is the brightest star in Aquila and the 12th brightest star in the sky. Altair is a type-A main sequence star with approximately 1.8 times the mass of the Sun and 11 times its luminosity. Altair has 1.79 times the Sun’s mass and an estimated radius between 1.63 and 2.03 times that of the Sun. The CHARA image was the first ever image of a star that provided visual confirmation of gravity darkening. Star type. FACTS. It’s possible that Altair has begun to utilize helium in the core, and therefore could be on the way towards becoming a subgiant star. Next is Altair, while Deneb appears much dimmer than its companions. Other observations in the infrared have confirmed Altair’s flattened shape. Altair’s equatorial radius was calculated to be about 2.03 solar radii and its polar radius 1.63 times solar, 25 percent smaller. Star type. 2.712), Okab (Zeta Aql, mag. " Altair is the brightest star in the constellation of Aquila (the Eagle). With apparent magnitudes of 3.87 and 2.7, Alshain and Tarazed are easily visible next to Altair on a clear night. The best time of year to observe the stars and deep sky objects of Aquila is during the month of August, when the Eagle flies high overhead in the evening for northern observers.

Join our Space Forums to keep talking space on the latest missions, night sky and more! While the name is Arabic (meaning Eagle), it also was noticed in areas such as India, where Altair and two nearby stars were sometimes referred to as footprints of the god Vishnu. The star’s Arabic name appeared in Egyptian astronomer Al Achsasi al Mouakket’s star catalogue, written in 1650, and was translated into Latin as Vultur Volans. Also, while Altair is 1½ times larger than Earth's sun, Vega is more than three times larger. Altair is a Subgiant Star type star. The star, which is in the constellation Aquila (the Eagle), is just 16.7 light-years from Earth, making it one of the closest naked-eye stars visible in the sky. However, this view is deceptive and illustrates the difference between magnitude and luminosity. Observations with the Palomar Testbed Interferometer (PTI) in 1999 and 2000 revealed that the star had an oblate photosphere as a result of its high rotation rate. 3.87), Eta Aquilae (mag. In science fiction, Altair 4 (a fictional planet of the star) was where the movie "Forbidden Planet" took place. Altair VI was the inhabited sixth planet of the Altair system.The system was located in Sector 9. Altair is a very fast spinner, with a rotational velocity of about 286 km/s, or 71.5 percent of its estimated breakup speed (400 km/s). Altair is one of the 58 stars selected for navigation.

Navigational stars are some of the brightest and most identifiable stars in the sky. Altair’s diameter at the equator is more than 20 percent greater than its diameter at the poles.  Altair was the first main sequence star for which rotational velocity was established from observations of the geometry of its photosphere. The meeting of the star-crossed lovers is celebrated during the annual Qixi Festival, held on the seventh day of the seventh month on the Chinese lunar calendar. Visit our corporate site.

The two stars are slightly fainter than Betelgeuse in Orion and Hadar in Centaurus, but they (usually) outshine the variable Aldebaran in Taurus, Antares in Scorpius and Spica in Virgo constellation. Based on the spectral type (A7IV-V) … The G-Cloud is located next to the Local Interstellar Cloud (the Local Fluff), through which our solar system is currently moving. The star’s polar axis is inclined by about 60 degrees to our line of sight. Published in 2001, the study gave an estimated rotational velocity (v sin i) of 210 ± 13 km s-1. Like Vega, it rotates very rapidly, with a projected rotational velocity of 286 km/s at the equator and a … This made Altair the first main sequence star other than the Sun to have its surface imaged. Alkaid is a young star of the spectral type B3 V, indicating a star bluish in colour and still on the main sequence, burning hydrogen into helium in its core. One of Altair's most interesting astronomical features is its variability, although it wouldn't be possible to see with the naked eye. In Micronesia, Altair is known as Mai-lapa, or “big/old breadfruit.” The Māori people of New Zealand knew the star as Poutu-te-rangi, or “the pillar of heaven,” while the Koori people in Victoria in Australia called it Bunjil, the wedge-tailed eagle (Australia’s largest predatory bird), and Tarazed and Alshain were known as black swans, his two wives. The production range of filtering cartridges has a wide variety of diameters, from 100 mm to 660 mm, widths up to 2000 mm. It was designed to be highly maneuverable at warp speeds, but suffered from unacceptably low power efficiency. Aquila contains several notable deep sky objects. Altair is located 16.73 light years from Earth in the G-cloud, a huge interstellar cloud of gas and dust. The USS Altair was an experimental Federation starship in the late 24th century. It is moving across the sky against the background of distant stars more quickly than most, and will displace itself by as much as a degree in only 5,000 years," wrote Jim Kaler, a professor emeritus of astronomy at the University of Illinois. Altair, also called Alpha Aquilae, the brighest star in the northern constellation Aquila and the 12th brightest star in the sky. It is the 12th brightest star in the night sky with an apparent magnitude of 0.77.

Altair is a white A star that, at a distance of under … Altair’s API is simple, friendly and consistent and built on top of the powerful Vega-Lite visualization grammar. One rotation takes about 9 to 10 hours. Altair is easy to identify because it is part of the Summer Triangle and has two relatively bright stars – Alshain and Tarazed – on either side. That is because Vega puts out more light; it is more luminous. In local lore, the wounded cod created a channel across southern Australia and moved to the sky as the constellation Delphinus.

Additionally, Altair's movements relative to other stars have astonished some astronomers: "Though seemingly ordinary, the star is not without its own striking characteristics. Altair is known as “the cowherd star” (Niú Láng XÄ«ng, 牛郎星). ALTAIR s.r.l. Altair is closer to us than Vega, but appears a bit dimmer. Wilson, credit: Ming Zhao, John Monnier. Altair finds its origins in Arabic and is derived from a phrase that means "the flying one." The Arabic name was also used for the asterism Altair forms with Alshain (Beta Aquilae) and Tarazed (Gamma Aquilae). The name Altair comes from the Arabic phrase an-nasr aá¹­-ṭāʼir, which means “the flying eagle.” The name was officially approved by the International Astronomical Union’s (IAU) Working Group on Star Names (WGSN) on June 30, 2016.

Altair is a main star in the constellation Aquila and makes up the constellation outline. The star is also rotating so rapidly — at nearly 185 miles (300 kilometers) a second at the equator — that it is at about 90 percent of the speed it would take to rotate fast enough to blow apart. They can only meet once a year when magpies create a bridge to allow them to cross the celestial river. Dr. Hiroshi Nakashima, Professor, Kyoto University I risultati ottenuti erano basati su osservazioni effettuate per mezzo del PTI, Palomar Testbed Interferometer , un sistema meno potente del CHARA, costituito da telescopi da 40 cm, separati da una distanza di 109 metri. Altair s.r.l. Gravity darkening was confirmed for Altair in 2001 after measurements with the Navy Prototype Optical Interferometer. Altair is a bright star in the northern summer sky that is one of the three stars that form an astronomical asterism called the Summer Triangle. Altair is the nearest of the three stars. The Summer Triangle and the Northern Cross, image: Wikisky. It appears brighter than Deneb, but not quite as bright as Vega.

Altair /ælˈtɛər/, designated α Aquilae (Latinised to Alpha Aquilae, abbreviated Alpha Aql, α Aql), is the brightest star in the constellation of Aquila and the twelfth brightest star in the night sky. These stars are used as standard candles to measure distances to star clusters and nearby galaxies. Deneb appears only one-third as bright as Vega, but it is, in fact, one of the greatest supergiant stars known. The system, which consisted of at least six planets, was of strategic importance to the Federation in the mid-23rd century. Image of the rapidly rotating star Altair, made with the MIRC imager on the CHARA Array on Mt.
