Neptune is the 8th planet in the Solar System, and the furthest from Earth’s sun. Light reflected off Neptune’s surface takes 4 hours, 20 minutes to reach Earth.
The larger of the two ‘ice giants’, Neptune has a thick blue atmosphere of hydrogen (80%) and helium (19%). Beneath its icy mantle, astronomers and physicists suspect that metre-wide diamonds rain down on a core of molten rock.
The planet Neptune takes its name from the Roman god of the sea, the equivalent of the Greek god Poseidon. Nymphs, monsters, and other deities of the wine-dark Greek sea lend their names to its 14 moons.
More than 80% of Earth’s oceans remain unexplored, unmapped, and unprotected. Like its heavenly brother, Neptune’s terrestrial domain is a mythical place – one of imagined terrors and swashbuckling legends.
Together, let’s explore our depths and our destinies, telling stories about the mysteries of our shared universe.
