Happy Birthday Neptune!

Hey Space Placers!

The beautiful and blue planet Neptune has completed 1 full orbit around the Sun since its' discovery on Spetember 23-24, 1846. Neptune was discovered as a result of the gravitational influences its had on the planet Uranus. Astronomers were able to calculate the predicted position of the unknown planet  and started searching. Neptune was found within 1 degree of the predicted positon.

Pretty amazing to consider all of this calculation was done by paper and pen - no calculators, no computers, no digital cameras, no computer controlled telescopes. Amazing and a tribute to the state of science at the time.
