HD 173416
, - bgcolor="#FFFAFA" HD 173416 is an intermediate-mass giant star in the constellation Lyra. It is a 6th magnitude star, relatively bright for its distance of about 440 light years from Earth. The star HD 173416 is named Xihe (羲和). The name was selected in the NameExoWorlds campaign by Nanjing, during the 100th anniversary of the IAU. Xihe is the goddess of the sun in the Chinese mythology and also represents the earliest astronomers and developers of calendars in ancient China. Planetary system In January 2009, a planet of the star was discovered. This object was detected using the radial velocity method by search programs conducted from the Xinglong Station in China and th Okayama Astrophysical Observatory(OAO) in Japan.

Radial Velocity Method
Doppler spectroscopy (also known as the radial-velocity method, or colloquially, the wobble method) is an indirect method for finding extrasolar planets and brown dwarfs from radial-velocity measurements via observation of Doppler shifts in the spectrum of the planet's parent star. 1,018 extrasolar planets (about 19.5% of the total) have been discovered using Doppler spectroscopy, as of November 2022. History Otto Struve proposed in 1952 the use of powerful spectrographs to detect distant planets. He described how a very large planet, as large as Jupiter, for example, would cause its parent star to wobble slightly as the two objects orbit around their center of mass. He predicted that the small Doppler shifts to the light emitted by the star, caused by its continuously varying radial velocity, would be detectable by the most sensitive spectrographs as tiny redshifts and blueshifts in the star's emission. However, the technology of the time produced radial-velocity meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hipparcos Objects
''Hipparcos'' was a scientific satellite of the European Space Agency (ESA), launched in 1989 and operated until 1993. It was the first space experiment devoted to precision astrometry, the accurate measurement of the positions of celestial objects on the sky. This permitted the first high-precision measurements of the intrinsic brightnesses (compared to the less precise apparent brightness), proper motions, and parallaxes of stars, enabling better calculations of their distance and tangential velocity. When combined with radial velocity measurements from spectroscopy, astrophysicists were able to finally measure all six quantities needed to determine the motion of stars. The resulting ''Hipparcos Catalogue'', a high-precision catalogue of more than 118,200 stars, was published in 1997. The lower-precision ''Tycho Catalogue'' of more than a million stars was published at the same time, while the enhanced Tycho-2 Catalogue of 2.5 million stars was published in 2000. ''Hip ...

G-type Subgiants
Gaea Gaea is one of the Elder Gods of Earth. Gaia Gaia, also known as the Guardian of the Universal Amalgamator, is a fictional superhero, depicted as possibly being a mutant or extraterrestrial. Created by Larry Hama, she first appeared in ''Generation X'' #37. Not much is known about Gaia's origin besides her having spent thousands of years chained to the Universal Amalgamator at the end of Time, a device that would be used to merge all sentient consciousnesses into one being.''Generation X'' #37 Gaia was apparently the safeguard that was supposed to prevent the Amalgamator from being activated by malicious people. She even claimed that her entire galaxy was wiped out at one point for her refusing to activate the Amalgamator.''Generation X'' #38 However, when M-Plate, the synthesis of Emplate and M, tried to have Synch use his power to tap into Gaia's and activate the Amalgamator, Everett refused.

HD 173416 B
HD 173416 b, also named Wangshu, is an extrasolar planet located approximately 440 light years away in the constellation of Lyra, orbiting the 6th magnitude G-type giant star HD 173416. This is planet is at least 2.7 times the mass of Jupiter and was discovered on January 10, 2009 by Liu ''et al.'' HD 173416 b orbits at 1.16 AU from the star. However, despite the fact that the planet orbits 16% further from the star than Earth does from the Sun, it has orbital period of only 323.6 days, compared to 365.25 days for Earth. This inverse relationship is caused by the parent star having twice the mass of the Sun, which increases the strength of its gravitational field. This evidence implies that when this star was on the main sequence, it was an A-type star. The planet HD 173416 b is named Wangshu (望舒). The name was selected in the NameExoWorlds campaign by Nanjing, during the 100th anniversary of the IAU. Wangshu is the goddess who drives for the Moon and also represents the ...

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or ...

Chinese Mythology
Chinese mythology () is mythology that has been passed down in oral form or recorded in literature in the geographic area now known as Greater China. Chinese mythology includes many varied myths from regional and cultural traditions. Much of the mythology involves exciting stories full of fantastic people and beings, the use of magical powers, often taking place in an exotic mythological place or time. Like many mythologies, Chinese mythology has in the past been believed to be, at least in part, a factual recording of history. Along with Chinese folklore, Chinese mythology forms an important part of Chinese folk religion. Many stories regarding characters and events of the distant past have a double tradition: ones which present a more historicized or euhemerized version and ones which present a more mythological version. Many myths involve the creation and cosmology of the universe and its deities and inhabitants. Some mythology involves creation myths, the origin of things, ...
