By 1845, Le Verrier had become interested in the motion of the planet Uranus. Uranus did not have the orbit scientists expected it to have based on their mathematical calculations.

Through mathematical calculations, Le Verrier predicted the presence of another planet beyond Uranus. The gravitational pull of this planet would explain the unusual motion of Uranus.

Le Verrier expected to be declared the sole discoverer of Neptune, but months prior to his calculations being completed John Couch Adams, an English mathematician, had accomplished the same feat. As a consequence, Le Verrier and Adams share the honor as Neptune's discoverers.
