(Redirected from Comet Lexell Anders Johan Lexell December 24 December 11 Julian calendar November 30 )) was a Swedish-Russian astronomer and mathematician . In Russian he is known as Andrei Ivanovich Leksel (ÐндÑей ÐÐ²Ð°Ð½Ð¾Ð²Ð¸Ñ ÐекÑелÑ). His name is also given as Anders Johann Lexell or even Johann Anders Lexell He emigrated to Russia in . He studied the motions of comets . He computed the orbit of comet D/1770 L1 (Lexell), and it is named after him although it was discovered by Charles Messier . This comet made the closest known approach to Earth by any comet in history (although asteroids have come closer), making it the first known near-Earth object ; the exact distance is not known but has been estimated to have been within 3 million km. Lexell showed that the comet had had a much larger perihelion distance until an encounter Jupiter in , and he predicted that, after encountering Jupiter again at an even closer distance two revolutions later, in , it would be altogether expelled from the inner solar system He was also the first to compute the orbit of Uranus soon after its discovery and realized from its orbit that it was a planet rather than a comet. He also found that Uranus was being perturbed and deduced the existence of another planet (the eventual

Lexell Biography of anders lexell (17401784) anders lexell is sometimes known bythe Russian version of his name which is Andrei Ivanovich lexell. http://www-groups.dcs.st-and.ac.uk/~history/Mathematicians/Lexell.html
Extractions: Version for printing Anders Lexell In 1768 Lexell was invited to St Petersburg. The St Petersburg Academy of Sciences had been founded by Catherine I, the wife of Peter the Great, in 1725 and Euler had worked there since 1727. By this time Euler was getting quite old, being 62 years of age when the young mathematician Lexell arrived in 1769. However, working in the same Academy as Euler and other high quality scientists was something which Lexell found exciting and enjoyable. Euler discussed research plans with Lexell and the other mathematicians at the Academy. They shared ideas while Lexell sometimes developed further ideas suggested by Euler , sometimes calculating tables, and compiling examples. For example Lexell is given full credit on the title page for his help with Euler 's 1772 publication Theoria motuum lunae, nova methodo pertractata.

Extractions: Anders Johan (sometimes in Russian: Andrei Ivanovich) Lexell was born on December 24, 1740 in Abo, then Sweden (now Turku, Finland), where he lived until 1763, and graduated at the university of Abo im 1760. In 1763, he became assistant professor at Uppsala Nautical School, in 1766 professor of mathematics. In 1768 he was invited to the St. Petersburg Academy of Science where he was appointed as professor of astronomy in 1771, and in succession of Euler, to the chair of mathematics in 1783. He died at St. Petersburg a year later, on December 11, 1784. From 1780 to 1782 he had undertaken a travel through Europe and visited Germany, France and England. Besides significant work in mathematics, mainly analysis and geometry, he contributed to astronomy his calculation of the solar parallax and the calculation of the orbits of several comets. Among these comets was one discovered by Charles Messier , the first for which a short period (5 1/2 years) was found. Lexell also found that it had passed very close to Jupiter and its moons, but while the comet changed its orbit significantly and could not be found later, the moons were uneffected; this led him to the conclusion that the comet's mass was extremely low. He also was among the first to calculate an orbit for planet Uranus as it was newly discovered by William Herschel on March 13, 1781.
