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.
Neptune was discovered because of anomalies in the orbit of Uranus, indicating that another planet's gravitational pull was affecting Uranus's orbit. This led to the prediction and eventual discovery of Neptune in 1846 by Urbain Le Verrier and John Couch Adams.
Neptune (the eighth and outermost planet) was discovered on September 23, 1846. It takes 164.79 Earth years to complete one orbit and will therefore only complete its first orbit since its discovery in 2011. It is also worth noting that while Pluto is not longer regarded as a planet (it is now a minor planet) it was discovered in 1930 and takes 248.09 Earth years to complete an orbit.
The plane with the smallest orbit is Mercury, and the planet with the largest orbit is Neptune.
The motion of the planets are elliptical motions
He discovered that avery planet has a ellipcial orbit, which means oval.
Uranus is the planet that was discovered beyond the orbit of Saturn. It was discovered on March 13, 1781 by William Herschel.

Uranus
Each planet is in its own orbit and obey's Kepler's laws of planetary motion. Newton later discovered that the Sun's gravity is what makes the planets move in their orbits in the way they do.
The moon Miranda orbits the planet Uranus and it was discovered in 1948. Uranus has a total of five moons.
After Neptune was discovered, they were claims that its orbit didn't seem to be as predicted. This led to the conclusion that it must be disturbed by another massive planet beyond it. Later Pluto was discovered, but it's mass was not large enough to disturb Neptune. For many years astronomers searched for another planet, but it was recently discovered that Neptune's orbit is not as perturbed as once thought, so the "need" for another planet is gone.
A moon that does not orbit a planet is called a "moonmoon" or "submoon." It would directly orbit a larger moon, which in turn orbits a planet. This scenario is theoretically possible but has not been observed in reality yet.

These are two additional moons of Pluto, that were recently discovered in orbit around the Dwarf Planet.
Comets don't orbit a planet, they orbit the sun.
