Heaven's Great General
Tian Dajiangjun () is a Chinese constellation () in the region of ''Bond (Chinese constellation), Lóu'' (). It contains 11 or 12 stars, in the Western constellations Andromeda (constellation), Andromeda and Triangulum. Its name is translated as "Heaven's Great General" or "Celestial Grand General". In older Western sources its name was transliterated as ''Teen Ta Tseang Keun'' or ''Tëen ta tsëang keun''. Richard Hinckley Allen, R. H. Allen based identification of Chinese star names by the English astronomer John Williams (astronomer), John Williams (1797–1874) and the naturalist John Reeves (naturalist), John Reeves. But Allen lacked last word ''kuen'' as ''Tien Ta Tseang'' and also transliterated it as ''Tsien Ta Tseang''.Allen (1963): p.416.

Chinese Constellation
Traditional Chinese astronomy has a system of dividing the celestial sphere into asterisms or constellations, known as "officials" ( Chinese ''xīng guān''). The Chinese asterisms are generally smaller than the constellations of Hellenistic tradition. The Song dynasty (13th-century) Suzhou planisphere shows a total of 283 asterisms, comprising a total of 1,565 individual stars. The asterisms are divided into four groups, the Twenty-Eight Mansions (, ''Èrshíbā Xiù'') along the ecliptic, and the Three Enclosures of the northern sky. The southern sky was added as a fifth group in the late Ming dynasty based on European star charts, comprising an additional 23 asterisms. The Three Enclosures (, ''Sān Yuán'') include the Purple Forbidden Enclosure, which is centered on the north celestial pole and includes those stars which could be seen year-round,Needham, J.Astronomy in Ancient and Medieval China.

She Shan Hill
Sheshan, known in Shanghainese as Zose, is a pair of hills in Songjiang District in western Shanghai, China. The two hills are distinguished as East and , although the more important western hill is also called Sheshan on its own. East Sheshan has an elevation of and West Sheshan has an elevation of , it is the highest point in Shanghai, there is a small valley between them. The area around the two hills is a forest park. Basilica It is surmounted by the ''Our Lady of China'' Catholic church, Sheshan Basilica, which was built there between 1922 and 1936 following the establishment of a chapel in 1867, soon replaced by a first church in 1871-1873 by French Jesuit missionaries. Services in the church are held in Chinese and Latin. The road to the top of Sheshan hill represents the stations of the cross Via Dolorosa (The Way of Suffering) that Christ took to his crucifixion. Every May pilgrims flock to the chapel and the holy road by the hundreds. Observatory The hill also h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

56 Andromedae
56 Andromedae, abbreviated 56 And, is a probable binary star system in the northern constellation of Andromeda. ''56 Andromedae'' is the Flamsteed designation. It has a combined apparent visual magnitude of 5.69, which is just bright enough to be dimly visible to the naked eye under good seeing conditions. The distance to this system can be ascertained from its annual parallax shift, measured at with the Gaia space observatory, which yields a separation of 330 light years. It is moving further from the Earth with a heliocentric radial velocity of +62 km/s and is traversing the celestial sphere at a relatively high rate of per year. This pair is positioned near the line of sight to the open cluster NGC 752, located away. The brighter primary is an aging giant star with a stellar classification of K0 III, having exhausted the hydrogen at its core and evolved off the main sequence.

Tau Andromedae
Tau Andromedae is a single star in the northern constellation of Andromeda. Its Bayer designation is Latinized from τ Andromedae, and abbreviated Tau And or τ And, respectively. The star has an apparent visual magnitude of +4.94, which is bright enough to be viewed from dark suburban skies. From parallax measurements made during the Gaia mission, the distance to this star can be estimated as roughly from Earth. The brightness of this star is diminished by 0.24 in magnitude due to extinction caused by intervening gas and dust. It is drifting closer to the Sun with a radial velocity of −14 km/s. The spectrum of this star matches a stellar classification of B5 III, with the luminosity class of III indicating that this is a giant star. It is radiating about 851 times the luminosity of the Sun from its photosphere at an effective temperature of 12,670 K. The star is an estimated 217 million years old and is spinning with a high projected rotational ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
50 Andromedae
Upsilon Andromedae (υ Andromedae, abbreviated Upsilon And, υ And) is a binary star located 44 light-years from Earth in the constellation of Andromeda. The system consists of an F-type main-sequence star (designated υ Andromedae A, officially named Titawin in the Amazigh language ) and a smaller red dwarf. , three extrasolar planets (designated Upsilon Andromedae b, c, d; named Saffar, Samh and Majriti, respectively) are believed to orbit υ Andromedae A. All three are likely to be jovian planets that are comparable in size to Jupiter. This was both the first multiple- planet system to be discovered around a main-sequence star, and the first multiple-planet system known in a multiple-star system. Nomenclature ''υ Andromedae'' ( Latinised to ''Upsilon Andromedae'') is the system's Bayer designation. Under the rules for naming objects in binary star systems, the two components are designated A and B. Under the same rules, the first planet discovered orbiting υ And ...

Consequently, the Chinese name for χ Andromedae itself is (, .) This is most likely a |
Omega Andromedae
Omega Andromedae (ω And, ω Andromedae) is a binary star system in the northern constellation of Andromeda. Parallax measurements made during the ''Gaia'' mission make this system to be approximately from Earth. Its apparent visual magnitude is +4.83, which makes it bright enough to be seen with the naked eye. The primary component has a stellar classification of F5 IVe. The IV luminosity class indicates that it is probably a subgiant star that is in the process of evolving away from the main sequence as the supply of hydrogen at its core depletes. However, Abt (1985) gives a classification of F3 V, suggesting it is an F-type main-sequence star. The measured angular diameter of the primary star is . At the system's estimated distance this yields a size of about 2.2 times that of the Sun. It is emitting about seven times solar luminosity from its outer atmosphere at an effective temperature of . This heat gives it the yellow-white-hued glow of an F-type star ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
