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.
Astronomers soon discovered a moon orbiting Neptune, but it took more than a century to discover a second one. Our knowledge of distant Neptune greatly increased from the scientific observations made during Voyager 2’s flyby in 1989, including the discovery of five additional moons and confirmation of dark rings orbiting the planet.
