Extractions: Friedrich Wilhelm Bessel Bessel, Friedrich Wilhelm (Minden, 1784-Königsberg, 1846), astrónomo y matemático alemán. A través de su interés por la navegación llegó a interesarse por la Astronomía de forma autodidacta. Construyó un sextante, con el que realizó observaciones, y remitió a Olbers sus resultados sobre la determinación de la órbita del cometa Halley de 1607; así consiguió plaza de inspector en un observatorio privado de Lilienthal. Más tarde, en 1810, se le confió la dirección del Observatorio de Königsberg, el cual supervisó su construcción. Se dedicó en principio a la determinación precisa de la Aberración, nutación, precesión, refracción e inclinación de la elíptica. En 1821 emprendió el estudio de las posiciones de las estrellas, en el que llegó a la 9.ª Magnitud elevando el número de estrellas catalogadas a 50.000. Sus observaciones con el heliómetro le condujeron al cálculo de la primera paralaje estelar, la de la estrella 61 Cygni (1829) proporcionando así la confirmación definitiva de la teoría por la que el Sol y no la Tierra es el centro del Sistema Solar. En su obra Astronomische Untersuchungen (Investigación astronómica) 1841-42, están contenidos la mayor parte de estos trabajos.

Extractions: German astronomer and mathematician, assistant to Schröter at Lilienthal, who became Director of the Königsberg Observatory in 1810. Bessel was a superb observer and made many important contributions to positional astronomy, including, in 1838, the first direct measurement of a star's distance, that of 61 Cygni , by trigonometric parallax . He argued against the existence of life on the Moon at a time when several notable compatriots of his, including Gauss Gruithuisen Littrow , and Olbers , were in the pro-selenite camp. In particular, he noted the sharpness with which stars are occulted by the Moon, indicating the absence of a lunar atmosphere. In a lecture, delivered in 1838, he took the supporters of pluralism to task for ignoring the astronomical evidence that our neighboring worlds (with the possible exception of Mars) are not suited to life as we know it: The moon is decisively different from the earth in the primary point of an atmosphere; the sun is of an entirely different nature; for Mercury and Venus we have found no basis for assuming a similarity; Mars appears to possess an atmosphere and summer and winter, even snow and ice; . . . Jupiter and Saturn are very dissimilar to the earth in the matter of which they consist . . .

Extractions: Ses principales contributions sont la construction d'appareils très précis pour le positionnement des étoiles et des planètes. Il effectue la première mesure d'une parallaxe stellaire. Il complète le catalogue de 75 000 étoiles jusqu'à la magnitude 9. Il raffine le calcul astronomique en créant de nouvelles méthodes appliquées au calcul de perturbation planétaire. On lui doit l'année-lumière comme unité de longueur. Ses tout derniers travaux ont trait à l'orbite de Neptune; il démontre que son orbite irrégulière ne peut être due uniquement à Jupiter, Saturne et Uranus et qu'il se pourrait qu'il y ait une autre planète. Pluton ne sera découverte qu'en 1930. À partir de 1840, sa santé se détériore. Après deux ans de souffrance, il meurt d'un cancer, non sans avoir eu la peine de voir mourir ses deux fils.

Extractions: Friedrich Wilhelm Bessel era un astronomo e matematico tedesco. E' ricordato soprattutto per la prima accurata misurazione della distanza di una stella. Nato a Minden, Bessel sopraintese la costruzione dell'Osservatorio di Königsberg di cui fu direttore dal 1813 fino alla sua morte. Tra il 1821 e il 1833 determinò la posizione delle stelle fino alla nona magnitudine, contribuendo alla compilazione di un catalogo di 50.000 stelle. Bessel fu il primo nel riuscire a determinare la parallasse e quindi la distanza di una stella (61 Cygni). Lo spostamento apparente della stella osservata a distanza di sei mesi, cioè dopo che la Terra ha percorso metà della sua orbita, fornì anche la conferma definitiva che è la Terra a girare attorno al Sole. Egli determinò il diametro, il peso e l'ellitticità della Terra (cioè la deviazione dalla forma sferica) e il suo nome è noto anche per una funzione matematica che trova numerosi impieghi in vari campi della fisica.

Extractions: Nel 1841 Federico Bessel (1784-1846), concludendo l'elaborazione di tutte le misure del grado effettuate fino ad allora, fissò l'ellissoide di rotazione terrestre dando i valori 6376,83 km per il semiasse maggiore e 6355,10 per quello minore (i valori attualmente adottati per l'ellissoide internazionale, o ellissoide di Hayford, sono rispettivamente 6378,388 e 6356,912 con una circonferenza meridiana di 40009,152 ed una circonferenza equatoriale di 40076,592 km). Nonostante le successive determinazioni della lunghezza della circonferenza terrestre, il valore del metro è stato lasciato invariato, restando definito come la lunghezza del campione conservato a Parigi
