Poseidon

Neptune is the ninth planet of the Sol system. Like Uranus, Neptune is an ice giant.

Physical characteristics
Neptune's meteorological activity is notably higher than Uranus. One of the most notable features Neptune sports is the Great Dark Spot - a storm similar to that of the Great Red Spot on Jupiter.

Neptune is also known to swap orbits with Pluto on occasion.

Moons
Neptune has 14 moons, each of which are named after the children of the Greek god Poseidon. The largest of these moons is Triton, known for its cryovolcanic activity that make impact craters on its frozen nitrogen surface a rarity.

It is estimated that 3.6 billion years from now, Triton will cross into Neptune's Roche limit and be destroyed.
