Neptune is the eighth and last planet in our solar system. Even though Neptune is a gas giant and has no solid surface in reality, on Futurama, the terrain of Neptune appears to be icy and solid. However, only its Northern Pole is portrayed in the episodes in which it is featured, which may indicate that only its north pole is icy.
- It is the smallest of the 4 gas giants.
- It has the fastest winds in the solar system.
- It has a "Great Dark Spot" similar to Jupiter's "Great Red Spot".
- It has 13 moons, the biggest being Triton.
