Neptune
Neptune is the eighth farthest planet from the sun, it is named from the ancient Roman's God of the sea. It is also known as the third largest planet in mass in the solar system. It is also seventeen times the mass of earth. Neptune was discovered on September 23, 1846, found by mathematical
prediction. It was discovered by someone observing the inaccurate orbit, thus they predicted that another planet must have been perturbing its orbit. Only one spacecraft has visited the planet of Neptune, and that is the spacecraft named Voyager 2, which flew by on August 25, 1989. Neptune's atmosphere is classified as a gas giant, being composed of mostly of hydrogen, helium, and traces of ice. Neptune itself is also composed of gas, but contains some liquids like water, ammonia, methane, and other compounds. Neptune's core is guessed by scientists to me composed of iron, nickel, and other silicates.
After the discovery of Uranus, it was noticed that its orbit was not as it should be in accordance with Newton's laws.
It was therefore predicted that another more distant planet must be perturbing Uranus' orbit.
