Abstract

Neither Uranus nor Neptune are visible to the naked eye, and it was the advent of the telescope that made their discovery possible. Sir William Herschel, arguably the father of observational astronomy, discovered Uranus by accident, using his home-made telescope, on 13 March 1781. However the prediction of its position proved difficult, even taking into account the perturbations produced by the other known planets and by 1845 astronomers began to suspect that the answer to the problem was due to another planet orbiting beyond Uranus.
