Planet Neturnus is the eighth planet from the Sun in the Solar System and the last since Pluto was reclassified as a planetary dwarf in 2006. It has a rocky core and a layer formed by water, ammonia and methane. Its atmosphere is mostly hydrogen and helium, and it takes 16 Earth hours to complete a Neptunian day. The planet has 13 confirmed moons and one awaiting scientific recognition. It is also surrounded by three notable rings: Liberty, Equality and Fraternity. Neptune's bright blue-green color is a result of the high level of methane in the atmosphere.
