Editing Johann Heinrich Lambert (section)

=== Astronomy ===
Lambert also developed a theory of the generation of the [[universe]] that was similar to the [[nebular hypothesis]] that [[Thomas Wright (astronomer)|Thomas Wright]] and [[Immanuel Kant]] had (independently) developed. Wright published his account in ''An Original Theory or New Hypothesis of the Universe'' (1750), Kant in ''Allgemeine Naturgeschichte und Theorie des Himmels'', published anonymously in 1755. Shortly afterward, Lambert published his own version of the nebular hypothesis of the origin of the [[Solar System]] in ''Cosmologische Briefe über die Einrichtung des Weltbaues'' (1761). Lambert hypothesized that the stars near the [[Sun]] were part of a group which travelled together through the [[Milky Way]], and that there were many such groupings ([[star system]]s) throughout the [[galaxy]]. The former was later confirmed by Sir [[William Herschel]]. In [[astrodynamics]] he also solved the problem of determination of time of flight along a section of orbit, known now as [[Lambert's problem]]. His work in this area is commemorated by the [[Asteroid]] [[187 Lamberta]] named in his honour.
