Neptune (), () is the eighth and last planet from the Sun in the Solar System. It is a gas giant planet with four hard-to-see rings. It is the fourth largest planet and third heaviest. It is 17 times heavier than Earth and is a little bit more heavy than Uranus. The planet was named after the Roman God of the Sea. The astronomical symbol for the planet is.

Neptune's atmosphere (a layer of gas floating above planets) is mostly made up of hydrogen and helium (two types of gases), with small amounts of methane that is makes the planet blue. Neptune's blue color is much more brighter compared to Uranus, which has a similar amount of methane, so there might be another reason why neptune is blue. Neptune also has the strongest winds of any planet in the solar system, measured as high as 2,100 km/h or 1,300 mph.

Neptune was discovered by astronomers, Urbain Le Verrier and John Couch Adams who were both honored for the discovery. The planet was the first to be discovered by mathematical calculations instead of using a telescope. Because of Uranus' weird movements in its orbit (the line which a planet follows in moveing), it made astronomers search for the new planet. The planet was visited by only one spacecraft, "Voyager 2" on August 25, 1989. Neptune once had a huge storm known as the "Great Dark Spot" which was discovered in 1989 by Voyager 2. However, the dark spot was not seen in 1994, and new spots were found since then. It is not known why the dark spot disappeared. However, N
