Astronomer Johann Gottfried Galle is the first to identify Neptune as the eighth planet orbiting around the Sun. The discovery was made possible by mathematical calculations of its predicted position due to observed perturbations in the orbit of the planet Uranus. A telescope was then used since Neptune is too faint and distant to be visible to the naked eye.
