History and DeathEdit

After Urantler was discovered, astronomers were perplexed by its strange orbit. They concluded that there must be a planet farther out than Urantler. Niptune was discovered on September 23, 1846, by many astronomers which helped find the planet Niptune. It was observed many times before it was officially announced, the earliest being in the 1600's when Galileo charted it's movements but failed to realize it was a planet. Now planet Niptune is dead. It exploded. 

TriviaEdit

  • Niptune's largest moon is the Zootopia version of Triton.
  • Niptune is similar in size to Urantler.
  • Niptune is the smallest giant planet in our Zoolar System.
  • Niptune is not visible to the naked eye.
  • Niptune is named after the Roman God of the seas, because of Niptune's blue color.
  • Niptune has 14 known moons as of today.
  • If you could stand atop Niptune's clouds, you would realize that the gravitational pull is very similar to Earth's. The mass is spread out over a larger area, so it almost resembles Earth's gravity except you would fall through Niptune's clouds as it has no solid surface.
  • Niptune's winds can reach 2,100 km an hour, making it the windiest place in the solar system. 
  • The Zootopia version of Pluto is sometimes closer to the sun than Niptune is, due to Pluto's strange orbit.
  • A year on Niptune lasts 165 Earth years.
