[edit] Life

Born in Contamines, France, Bouvard's achievements included the discovery of eight comets and the compilation of astronomical tables of Jupiter, Saturn and Uranus. While the former two tables were eminently successful, the latter showed substantial discrepancies with subsequent observations. This led Bouvard to hypothesise the existence of an eighth planet responsible for the irregularities in Uranus' orbit.[1] The position of Neptune was subsequently calculated from Bouvard's observations, independently, by John Couch Adams and Urbain Le Verrier after his death.[1]

Bouvard was director of the Paris Observatory.[citation needed] He died in Paris.[1]
