Lets All Observe Neptune’s First Year Anniversary

September 23, 2011 marks the 165th anniversary of the discovery of Neptune by Johann Galle of the Berlin Observatory based on calculations made by LaVerrier in France. The discovery took place in 1846. Because it takes Neptune 165 years to orbit the sun, this year marks the first full “year” or trip around the sun since Neptune’s discovery.
