Roger Black: "I've got two Neptunes here, that can't be right, can it?"
Mykew Hadeline: "Aaaaah, when two Neptunes appear in the sky, it's probably being mistaken for Pluto, Roger...."
— Roger and Hadeline working on their Science homework[src]

Neptune is a planet in the Solar System. It was civilized in 1780. It orbits alongside the planetoid Pluto at times according to Mykew Hadeline.


During the Revolutionary War in 1780, undisclosed non-Humans began what became known as the Civilization of Neptune, building roads, schools, and the like on the planet and making Neptune the last planet in the solar system to be civilized.

Neptune was discovered by humans based on Earth in 1846.

Neptune is talked about in Foresight, such as in 1992 when Mrs Sintra pointed out the fascinating angle Mars made with the planet with her orrery,[1] and is also be taught in Astronomy class.

Behind the scenesEdit

Neptune is named after the Roman sea god, who was known as Poseidon in Greek times. He is the father of the title character of the Percy Jackson & the Olympians series.
