gamma ursae minoris

In Inuit astronomy, the three brightest stars of Ursa Minor – Polaris, Kochab, and Pherkad, were known as the Nuutuittut – the “never moving”, though the term is often used for Polaris alone, rather than the trio of stars. Pherkad is located in the constellation Ursa Minor, the Little Bear. ... Gamma Ursae Minoris. Pherkad (Gamma Ursae Minoris): 487 light-years from Earth, and about five times the mass of the sun. The planet may in fact be a brown dwarf. Gamma itself is a blue-white giant star of magnitude 3.0, 480 light-years away. Pherkad and its brighter neighbour Kochab are known as Guardians of the Pole. Consequently, the Chinese name for Gamma Ursae Majoris itself is 北斗三 (Běi Dǒu sān, English: the Third Star of Northern Dipper) and 天璣 (Tiān Jī, English: Star of Celestial Shining Pearl). [5] The secondary star is a K-type main-sequence star that is 0.79 times as massive as the Sun, and with a surface temperature of 4,780 K.[3], "Phad" redirects here. For scroll painting style, see. With an apparent magnitude of 3.05, it is the third brightest star in the constellation, after Polaris and Kochab.

Gamma Ursae Minoris is an A-type star with an apparent magnitude of 3. The Big Dipper (bottom centre) and Little Dipper, with Kochab and Pherkad visible near the centre of the image. The Little Dipper can be found using the stars of the bigger and brighter Big Dipper. With an apparent magnitude of 5.15, it is visible next to its brighter neighbour in exceptionally good conditions. Beta Ursae Minoris formed around millions of years ago from an interstellar medium of gas and dust. Be warned. De Pherkad (och Pherkab) ass d'Bezeechnung vum Stär γ Ursae Minoris (Gamma Ursae Minoris). Pherkad and its brighter neighbour Kochab form the end of the Dipper’s bowl. Because of its moderate brightness, Pherkad should be easily visible from locations with dark skyes, while it can be barely visible, or not visible at all, from skyes affected by light pollution. Gamma itself is a blue-white giant star of magnitude 3.0, 480 light-years away. Unlike its big brother, the asterism is not easy to spot from light-polluted areas because its middle four stars are fainter than magnitude 4.00. Its brightness has been reported to vary by a few tenths of magnitude over a period of 3.43 hours. In Chinese astronomy, the North Pole asterism is one of the mansions of the Purple Forbidden Enclosure, which represents the imperial palace. It has the traditional name Pherkad, which derives from the Arabic فرقد farqad "calf", short for aḫfa al farkadayn "the dim one of the two calves", Pherkad and Kochab. 3.05), Epsilon Ursae Minoris (mag.

Showing page 1. The star Beta Ursae Majoris is separated from Gamma Ursae Majoris by 11.0 ly (3.4 pc).[17]. The name Ahfa al Farkadain has traditionally been used for the fainter Zeta Ursae Minoris. Like the larger bear constellation (Ursa Major), Ursa Minor is one of the 48 Greek constellations, first catalogued by the astronomer Claudius Ptolemy of Alexandria in his Almagest in the 2nd century CE. Delta Scuti stars are pulsating variables whose brightness varies as they contract and expand. [14] Based upon parallax measurements with the Hipparcos astrometry satellite,[15][16] it is located at distance of around 83.2 light-years (25.5 parsecs) from the Sun.[1]. Zeta Ursae Minoris (ζ UMi) - mag. To the Hindus this star was known as Pulastya, one of the Seven Rishis. Pherkad, along with Kochab, form the end of the dipper pan of the Little Dipper.

Gamma Ursae Minoris (γ Ursae Minoris, Gamma UMi, γ UMi) is a main sequence star in the constellation of Ursa Minor, the little bear. Pherkad is part of the Chinese North Pole asterism, also formed by Kochab, 5 Ursae Minoris, 4 Ursae Minoris, and Σ 1694 (Struve 1694) in the constellation Camelopardalis. The two are separated by an estimated distance of 8.55 ly (2.62 pc); much closer than the two are from the Sun. Pherkad is the third brightest star in Ursa Minor. Ursa Major: Alkes A line extended from Merak through Dubhe leads to Polaris. γ Ursae Majoris (Latinised to Gamma Ursae Majoris) is the star's Bayer designation. The constellation was introduced to the Greeks (or possibly created) by the 6th century BCE Greek philosopher Thales of Miletus, who found its stars useful in navigation. The star is sometimes also called "Pherkad", "Phecda" or "Phad" (from the Arabic fakhð ad-dubb, “the thigh of the bear”).
