About The Planets In Our Solar System

Neptune is not visible to the unaided eye and is the only planet in the Solar System found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to hypothesise that its orbit was subject to gravitational perturbation by an unknown planet. After Bouvard's death, the position of Neptune was predicted from his observations, independently, by John Couch Adams and Urbain Le Verrier.

Jupiter's formation was likely influenced by a number of factors, including the temperature and composition of the early solar system, the presence of other planets, and the gravitational forces at play. It is likely that Jupiter's formation was a complex and dynamic process that took place over a long period of time.
