HD 16175
HD 16175 is a 7th magnitude G-type star with temperature about 6000 K located approximately 196 light-years away in the Andromeda constellation. This star is only visible through binoculars or better equipment; it is also 3.3 times more luminous, is 1.34 times more massive, and has a radius 1.66 times bigger than our local star.

Ethiopia, , om, Itiyoophiyaa, so, Itoobiya, ti, ኢትዮጵያ, Ítiyop'iya, aa, Itiyoppiya officially the Federal Democratic Republic of Ethiopia, is a landlocked country in the Horn of Africa. It shares borders with Eritrea to the north, Djibouti to the northeast, Somalia to the east and northeast, Kenya to the south, South Sudan to the west, and Sudan to the northwest. Ethiopia has a total area of . As of 2022, it is home to around 113.5 million inhabitants, making it the 13th-most populous country in the world and the 2nd-most populous in Africa after Nigeria. The national capital and largest city, Addis Ababa, lies several kilometres west of the East African Rift that splits the country into the African and Somali tectonic plates. Anatomically modern humans emerged from modern-day Ethiopia and set out to the Near East and elsewhere in the Middle Paleolithic period.

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. ''Hipparcos'' ...

HD 96167
HD 96167 is a double star system with an exoplanetary companion in the southern constellation of Crater. The apparent visual magnitude of this system is 8.09, which is too faint to be readily visible to the naked eye. It is located at a distance of approximately 279 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +12 km/s. The primary component, designated HD 96167 A, is an ordinary G-type main-sequence star with a stellar classification of G5V. It has also been classified as a subgiant star, suggesting it is somewhat more evolved having exhausted the hydrogen at its core. The star has an absolute magnitude of 3.41, placing it about a magnitude above the main sequence. It is metal rich and is around six billion years old. This star is larger, brighter and more massive than the Sun. A faint co-moving stellar companion, component HD 96167 B, was detected in 2014 at a projected separation 506 AU from the pri ...

HD 16175 B
HD 16175 b is an extrasolar planet located approximately 195.6 light-years away in the constellation of Andromeda, orbiting the star HD 16175. This planet masses 4.8 times that of Jupiter. However, the mass is only a minimum since the inclination of the orbit is not known. This planet orbits at about 2.2 astronomical units, taking 2.73 years to revolve around the star. The orbit of the planet is highly noncircular with an eccentricity at 0.64. The planet HD 16175 b is named Abol. The name was selected in the NameExoWorlds campaign by Ethiopia, during the 100th anniversary of the IAU. Abol is the first of three rounds of coffee in the Ethiopian traditional coffee ceremony. Discovery The discovery was made using radial velocity measurements taken between November 2004 and March 2009 with the Coudé Auxiliary and C. Donald Shane telescopes at Lick Observatory.

Extrasolar Planet
An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917 but was not recognized as such. The first confirmation of detection occurred in 1992. A different planet, initially detected in 1988, was confirmed in 2003. There are many methods of detecting exoplanets. Transit (astronomy), Transit photometry and Doppler spectroscopy have found the most, but these methods suffer from a clear observational bias favoring the detection of planets near the star; thus, 85% of the exoplanets detected are inside the tidal locking zone. In several cases, List of multiplanetary systems, multiple planets have been observed around a star.

Coffee
Coffee is a drink prepared from roasted coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulant, stimulating effect on humans, primarily due to its caffeine content. It is the most popular hot drink in the world. Seeds of the ''Coffea'' plant's fruits are separated to produce unroasted green coffee beans. The beans are Coffee roasting, roasted and then ground into fine particles that are typically steeped in hot water before being filtered out, producing a cup of coffee. It is usually served hot, although chilled or iced coffee is common. Coffee can be prepared and presented in a variety of ways (e.g., espresso, French press, caffè latte, or already-brewed canned coffee). Sugar, sugar substitutes, milk, and cream are often used to mask the bitter taste or enhance the flavor. Though coffee is now a global commodity, it has a History of coffee, long history tied closely to food traditions around the Red Sea. The earliest credible evidence of coffee d ...

International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
