Neptune: Characteristics and Discoveries

Neptune, the most distant planet in our solar system, was discovered through mathematics by Urbain Le Verrier. Voyager 2, the only spacecraft to visit Neptune, revealed its unique features, including the Great Dark Spot and new moons. Neptune's atmosphere is composed mainly of hydrogen, helium, and methane, giving it a vivid blue color. Its interior is a complex structure with extreme pressure and temperature, possibly containing a diamond ocean. Despite our understanding, Neptune remains one of the least explored planets, holding many mysteries for future research.
