The mysterious birthday Neptune


Neptune is approximately 4400 million kilometers away from Earth. Neptune is about to celebrate its first birthday. On July 12 will be a year-Neptunian-terrestrial or 164.79 years since its discovery on September 24, 1846. But why do we know so little about the distant planet?

At approximately 4400 million kilometers from Earth lies Neptune, the first planet in the solar system to be discovered deliberately. After classification of the planet Uranus in 1780, astronomers have been puzzled by his strange orbit. Scientists concluded that either Isaac Newton's laws had a fundamental flaw or something else-another-planet Uranus was pulling its expected orbit. And so began the search for the eighth planet.
