	Alexis Bouvard - Wikipedia, the free encyclopedia
		Alexis Bouvard (June 27, 1767 – June 7, 1843) was a French astronomer, born in Contamines, France.
		Bouvard's achievements included the discovery of eight comets and the compilation of astronomical tables of Jupiter, Saturn and Uranus.
		This led Bouvard to hypothesise the existence of an eighth planet responsible for the irregularities in Uranus' orbit.

		In 1820 Alexis Bouvard of Paris constructed tables of the motion of Jupiter, Saturn and Uranus, based upon a discussion of observations up to that year.
		Using the mutual perturbations of these planets as developed by Laplace in the Mecanique Celeste, he was enabled satisfactorily to represent the observed positions of Jupiter and Saturn; but the case was entirely different with.
		In 1837 Bouvard, in conjunction with his nephew Eugene, was again working on the problem; but it does not seem that they went farther than to collect observations and to compare the results with Bouvard's tables.

		Bouvard's achievements included the discovery of eight comets and the compilation ofastronomical tables of Jupiter, Saturn and Uranus.
		While the former two tables were eminently successful, the latter showed substantial discrepancieswith subsequent observations.
		This led Bouvard to hypothesise the existence ofan eighth planet responsible for the irregularities in Uranus ' orbit.

		1767: On 27 June 1767, Alexis Bouvard was born.
		Bouvard was a French astronomer and director of the Observatoire de Paris, who is noted for discovering eight comets and writing Tables astronomiques of Jupiter and Saturn (1808), and of Uranus (1821).
		Bouvard's tables accurately predicted orbital locations of Jupiter and Saturn, but his tables for Uranus failed, leading him to hypothesise that irregularities were caused by an unknown perturbing body.

	Alexis Bouvard (1767-1843)
		En 1822, avec Alexis Bouvard, né à Les Contamines-Montjoie (74170), au hameau dit : "Les Hôches" le 27 juin 1767,l'Observatoire voit nommé à sa tête un astronome observateur, qui d'ailleurs y habitait depuis 1793 et qui y resta jusqu'à sa mort, le 7 juin 1843.
		Bouvard a en effet calculé les Nouvelles Tables des Planètes Jupiter et Saturne (1808) et, plus tard, des tables pour la planète Uranus (1821).
		Si l'hypothèse de Bouvard ne rencontra que scepticisme de son vivant, ce n'en était pas moins la bonne, et on lui a rendu justice depuis.

	The Comets Of Caroline Herschel
		Her brother, William Herschel, noted that the comet was visible to the naked eye, while Alexis Bouvard compared its brightness to M31, the Andromeda Galaxy.
		This time, the comet was first seen on the night of 19th October, 1805 by European observers Jean Louis Pons, Johann Sigismund Huth, and Alexis Bouvard.
		Thus, were it not for an inadequate number of accurate observations preventing an early reliable orbit calculation, periodic comet Encke could have easily had the alternate name of periodic comet Herschel....or comet Mechain...or comet Pons-Huth-Bouvard.

		They began going over the star catalogues of earlier observers and found that the planet, named Uranus by the German astronomer Johann Elert Bode, had actually been seen 20 times prior to 1781, including as early as 1690, but misidentified as a star.
