Neptune is the eighth and outermost known planet in our solar system. It was discovered in 1846 by the German astronomer Johann Gottfried Galle on the basis of calculations from orbital perturbations of Uranus by the French mathematician Urbain Le Verrier. Neptune is an average of 4.5 billion kilometres from the Sun. From Earth, it has an apparent diameter of about 2 angular seconds. With a diameter of just under 50,000 kilometres, Neptune has almost four times the diameter of Earth and about 58 times the volume of Earth. After Jupiter, Saturn and Uranus, Neptune is the fourth largest planet in the solar System.
