All the Outer Planets have rings

This model, all the planets look about the same size.

• Is a huge, blue planet in our solar system, and it's the eighth planet from the Sun. It's called a "gas giant" because it's mostly made up of gases like hydrogen and helium.

• It has big dark spots called "storms" that are even bigger than Earth!

• Neptune's beautiful blue color comes from a gas called methane in its atmosphere.

​Neptune

Discovered by Math: Neptune was actually discovered because of math! Scientists noticed that Uranus wasn't following its predicted path exactly, so they used math to figure out there must be another planet out there tugging on the other planet. That's how they found Neptune!

• it's revolution (day) is 16 Earth hours, and it's orbit (year) is 165 Earth years

Neptune: Interesting Facts

-Most violent weather

-Triton - moon that orbits planet backward

-Named after Roman god of the sea

Neptune - "Windy Planet"

• A very cold, blue planet with visible clouds in the atmosphere

• Neptune's interior is still hot, releasing energy that rises and causes clouds and storms

• Once had a "Great Dark Spot" storm, similar to Jupiter

• Voyager 2 probe showed the largest moon, Triton, is covered in nitrogen ice
