Facts and Info about the Planet Neptune
Neptune was the Roman Mythological God of the Sea and earthquakes, he was also called the Earth-shaker! Neptune was first correctly observed by Galle and d'Arrest in 1846 following predictions by the English Astronomer John Couch Adams and the French Astronomer Le Verrier, the result of these predictions when they were confirmed was an international dispute between the English and French as to who should in fact be credited with the prediction and given the right to name the new Planet! We now jointly credit both Astronomers so at least the dispute is resolved!
