Johann Georg Palitzsch
Johann Georg Palitzsch (11 June 1723 in [modern Dresden], Electorate of Saxony, Holy Roman Empire) – 21 February 1788 in Prohlis) was a German astronomer who became famous for recovering Comet 1P/Halley (better known as Halley's Comet) on Christmas Day, 1758. The periodic nature of this comet had been deduced by its namesake Edmond Halley in 1705, but Halley had died before seeing if his prediction would come true. Raised to become a successful farmer under a strict stepfather, Palitzsch secretly studied as much astronomy as he could from the books he could afford. He learned contemporary astronomy from the book “Vorhof der Sternwissenschaft” (“The Forecourt of Astronomy”) by Christian Pescheck. He learned Latin and, at age 21, inherited the farm, which allowed him to construct his own botanical garden, library, laboratory, and museum. He received support from various benefactors, including the future Frederick Augustus I of Saxony, King. But the Seven Years' ...

Maximilian Hell
Maximilian Hell () (born Rudolf Maximilian Höll; May 15, 1720 – April 14, 1792) was an astronomer and an ordained Jesuit priest from the Kingdom of Hungary. The lunar crater Hell is named after him.

He was the third son from the second marriage of his father Matthias Cornelius Hell (Matthäus Kornelius Hell) and his mother Julianna Staindl. The couple had a total of 22 children. Registry entries indicate that the family was of German descent, while Maximilian Hell later in life (ca. 1750) is known to declare himself as Hungarian. but his mother tongue was German. Even so, Hell considered himself a Hungarian. The place of birth of Maximilian's father is unknown; the settlements Körmöcbánya (today Kremnica), Schlagenwald, (today Horní Slavkov) or Schlackenwerth (today Ostrov nad Ohří) are most frequently given. ...

Asteroid
An asteroid is a minor planet—an object larger than a meteoroid that is neither a planet nor an identified comet—that orbits within the Solar System#Inner Solar System, inner Solar System or is co-orbital with Jupiter (Trojan asteroids). Asteroids are rocky, metallic, or icy bodies with no atmosphere, and are broadly classified into C-type asteroid, C-type (carbonaceous), M-type asteroid, M-type (metallic), or S-type asteroid, S-type (silicaceous). The size and shape of asteroids vary significantly, ranging from small rubble piles under a kilometer across to Ceres (dwarf planet), Ceres, a dwarf planet almost 1000 km in diameter. A body is classified as a comet, not an asteroid, if it shows a coma (tail) when warmed by solar radiation, although recent observations suggest a continuum between these types of bodies. Of the roughly one million known asteroids, the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 astronomical unit, AU ...

Moon
The Moon is Earth's only natural satellite. It Orbit of the Moon, orbits around Earth at Lunar distance, an average distance of (; about 30 times Earth diameter, Earth's diameter). The Moon rotation, rotates, with a rotation period (lunar day) that is synchronized to its orbital period (Lunar month#Synodic month, lunar month) of 29.5 Earth days. This is the product of Earth's gravitation having tidal forces, tidally pulled on the Moon until one part of it stopped rotating away from the near side of the Moon, near side, making always the same lunar surface face Earth. Conversley, the gravitational pull of the Moon, on Earth, is the main driver of Earth's tides. In geophysical definition of planet, geophysical terms, the Moon is a planetary-mass object or satellite planet. Its mass is 1.2% that of the Earth, and its diameter is , roughly one-quarter of Earth's (about as wide as the contiguous United States). Within the Solar System, it is the List of Solar System objects by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vallis Palitzsch
The Vallis Palitzsch is a geological structure of the surface of the Moon. The name of the valley was given in 1964 by the International Astronomical Union and comes from the adjacent crater, which in turn was named after the German astronomer Johann Georg Palitzsch (1723–1788).

Palitzsch (crater)
Palitzsch is a lunar impact crater that is located in the southeast part of the Moon, near the southeast rim of the crater Petavius. Just to the southwest of Palitzsch is Hase, while to the east-southeast is Legendre. The northeast rim of Palitzsch forms the southern end of Vallis Palitzsch, a lunar valley that follows the eastern rim of Petavius for a distance of about 110 kilometers. The crater rim is relatively low and inconspicuous, while the floor forms a depression in the surface that follows the contours of the neighboring valley. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Palitzsch. Due to its rays, Palitzsch B is mapped as part of the Copernican System.The geologic history of the Moon, 1987, Wilhelms, Don E.; with sections by McCauley, John F.; Trask, Newell J.

Battle Of Dresden
The Battle of Dresden (26–27 August 1813) was a major engagement of the Napoleonic Wars. The battle took place around the city of Dresden in modern-day Germany. With the recent addition of Austria, the Sixth Coalition felt emboldened in their quest to expel the French from Central Europe. Despite being heavily outnumbered, French forces under Napoleon scored a victory against the Army of Bohemia led by Generalissimo Karl von Schwarzenberg. However, Napoleon's victory did not lead to the collapse of the coalition, and the weather and the uncommitted Russian reserves who formed an effective rear-guard precluded a major pursuit. Three days after the battle, the Coalition surrounded and destroyed a French corps advancing into their line of withdrawal at the Battle of Kulm. Prelude On 16 August, Napoleon had sent Marshal Saint-Cyr's corps to fortify and hold Dresden in order to hinder coalition movements and to serve as a possible base for his own manoeuvres. He planned to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Williams (poet)
Francis Williams ( – ) was a Jamaican polymath, scholar, astronomer and poet who was one of the most notable free black people in Jamaica. Born in Kingston, Jamaica, into a slaveholding family, Williams subsequently travelled to England where he officially became a British subject. After returning to Jamaica, he established a free school for free people of colour in Jamaica. His portrait is considered to be the earliest known example in the canon of western art to have been commissioned by a known Black person to record their own intellectual achievements. Due to poor archival conditions, most information about Williams comes from a lengthy racist attack on him by his white contemporary Edward Long, and from the portrait itself, which displays some of Williams' library and shows that he had observed the return of Halley's Comet which confirmed Newton's laws of motion. The portrait was purchased by Long after Williams' death. Early life Francis Williams was born in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Its tropical climate led to the development of a plantation economy focused primarily on sugar; slaves from East Africa were imported as fieldworkers, followed by Malays, Annamite, Vietnamese, Chinese, and Indians as indentured laborers. Today, the greatest proportion of the population is of mixed descent, while the predominant language is Réunion Creole, though French remains the sole official language.
