Neptune is the 8th planet out from the Sun.
Adams and Leverrier predicted the position of Neptune based on its effects on the orbit of Uranus.
Adams and d'Arrest
Adams and Leverrier both predicted the position of Neptune based on gravitational disturbances observed in the orbit of Uranus.
I really don't know
Adams and Leverrier predicted the position of Neptune by observing the gravitational effects it had on other celestial bodies, such as Uranus. They used mathematical calculations to determine where Neptune should be located in order to explain these observed effects.
The astronomer Galle, assisted by d'Arrest, discovered Neptune. Credit is also given to Adams and Le Verrier. They were mathematicians who predicted the position of Neptune. Le Verrier persuaded astronomers to search for the new planet.
They are all changing position all the time. The slowest is Neptune, which is travelling at 5.4 kilometres per second.
Earth is number 3.
Neptune
Neptune is the eighth planet from the sun; the furthest in our galaxy excluding Pluto, the second-furthest including it. Neptune is about 2,794 million miles (4,496.6 million kilometres) away from the sun. The planet immediately closer to the sun than Neptune is Uranus.
Yes, planet Neptune is named after the Roman god of the sea, Neptune. In Roman mythology, Neptune was the god of water and the sea. The planet's name reflects its striking blue color and its position as the farthest known planet from the sun at the time of its discovery.
