Neptune
Neptune was discovered in 1846 through observations of Uranus. Uranus' orbit was seen to appear to alter slightly through the gravitational effect of another planet, which turned out to be Neptune.
Astronomers noted that Uranus was not quite following the orbit predicted fro it. They hypothesized that the gravity of an unseen planet was affecting Uranus's orbit.
Astronomers saw some deviations from the expect orbit of the planet Uranus. Based on these deviations, some theorized that Uranus was being pulled out of its expect orbit by another planet, which turned out be Neptune.
Neptune's orbit and Uranus' orbit are never meeting, but Pluto and Neptune do have their orbits cross. :)

Neptune at the moment.However, because of it's orbit it sometimes comes between Uranus and Neptune.

The 8th planet : Neptune.
Neptune's place in orbit is relatively after Uranus's orbit. It being the eighth and final planet in our solar system (Pluto is not a planet), Neptune crosses with Pluto in the orbit making it the ninth planet until Pluto was kicked out.

In the traditional diagram of the Solar System Uranus is before Neptune. In reality, the planets are not in a line but at different points around the Sun as they orbit it, so it is the path of Uranus's orbit that lies before Neptune.

No. That would be Uranus.
Astronomers had noticed unexpected changes in the orbit of Uranus: the only explanation was another planet. Detailed study of the orbit of Uranus led to estimates about the size and location of Neptune.
