Tumbling Stone 2 - Focus On Comets: Lexell anders lexell (sometimes known by the Russian version of his name, Andrei Ivanovichlexell) was born on 24, December 1740 in Sweden and died on 11 December 1784 http://spaceguard.rm.iasf.cnr.it/tumblingstone/issues/num2/comet.htm
Extractions: M any of the ideas at the heart of our current understanding of the motion of NEOs date back to the XVIIIth and XIXth century, and are based on the study of the orbit of a single, exceptional body, the comet discovered on the night between 14 and 15 June 1770 by Messier, one of the most famous comet hunters of all times ( click here to know more about comets T he comet was heading right towards the Earth; within a few days, starting from 21 June, it became visible to the naked eye, reaching the second magnitude three days later. The minimum distance from the Earth was reached on 1 July, at about six times the lunar distance, and in a few more days the comet became not visible due to its proximity to the Sun; Pingré computed an ephemeris for its recovery based on a parabolic orbit, as it was then customary, and Messier was able to see the comet again starting from the beginning of August. Charles Messier T he comet was then observed until the first days of October. A serious problem soon became clear to astronomers: although the ephemeris by Pingre' had allowed the recovery of the comet in August, it was clearly incapable of accounting for the entire set of observations. Prosperin tried to use three parabolas to fit separately the observations of June, August, and September, but this was evidently unsatisfactory, and unjustifiable from the point of view of celestial mechanics.

Extractions: T he work of Johann Anders Lexell on the periodic comet that bears his name was brilliant and innovative, but did not put an end to the investigations on the motion of that extraordinary object. About seventy years later, in the early forties of the XIX century, Urbain Le Verrier reexamined the subject from the beginning, asking himself a question that previous astronomers had essentially avoided. The question was about the reliability of the orbit computed for the comet: did the available observations determine uniquely the orbital elements? ( click here to know more about the orbital elements A t that time the work of Gauss on the recovery of the first asteroid, Ceres ( see T.S. number 1: " Ceres: the missing planet?" ), was a `fait accompli' and, as a consequence, the quantitative treatment of observational errors in the determination of orbits had become a well posed mathematical problem. While working on comet Lexell, Le Verrier was also working on the determination of the orbit of the planet perturbing Uranus. When that planet was discovered (and named Neptune), at the end of the decade, Le Verrier became a celebrity. A portrait of Le Verrier L et us go back to Lexell's comet. Le Verrier critically examined again the available observations, and identified a subset of them that he trusted; he then tried to compute an accurate orbit for the comet, taking also into account the gravitational action of the Earth. After many computations, described in detail in his papers of 1844, 1848 and 1857, he realized that it was not possible to determine a unique `best' orbit for the comet, since the constraints given by the observations were insufficient.

Extractions: Charles Messier nació en Badonvillier, Lorraine, Francia, el 26 de junio de 1730 en una modesta familia como el décimo de 12 hermanos. Inicia su afición y pasión por la astronomía a los 14 años de edad cuando tiene la oportunidad de observar un cometa en el año de 1744 y el eclipse lunar de 1748. El astrónomo de la marina Joseph Nicolas Delisle lo contrata en 1751 para que realizara copias de mapas geográficos y es en esta época en que comienza sus primeras observaciones en el observatorio del Hotel de Cluny. Hacia el año 1757 utilizando cálculos de Delisle inicia la labor astronómica por la cual a sido reconocido en la historia de la astronomía que fue la búsqueda de cometas, en ese año utilizando cálculos realizados por Delisle revisó el cielo encontrando al cometa Halley. Durante esta búsqueda detecto la presencia de múltiples objetos cuya apariencia era muy similar al de un cometa. El 28 de agosto de 1758 comenzó a catalogar los objetos similares a cometas con el fin de que no tuviera confusiones posteriores en sus observaciones. El primer objeto que incluyó en la lista Fue la Nebulosa del cangrejo en Tauro y que se catalogó como objeto Messier 1 (M 1). Durante el año de 1755 descubrió y catalogó los objetos de M2 a M40. En 1763, descubrió el cometa 1763 - Messier y el siguiente cometa 1764 - Messier, el 3 de enero de 1764.
