pluto's orbital period is 247.7 years, very close to one and one -half times Neptune's .thus pluto makes two orbit's around the sun for every three made by Neptune.This match of orbital period may have created a cumulative gravitational attraction on Pluto that "tugged" it into it's orbit.
Astronomers believe that Pluto is strongly influenced by Neptune due to their orbital dynamics. Despite Pluto's highly elliptical orbit, which brings it closer to the Sun than Neptune for 20 years of its 248-year orbital period, their orbits are locked in a 3:2 resonance. This means that for every two orbits Pluto completes, Neptune completes three, preventing them from colliding. Additionally, computer simulations and observations of their gravitational interactions further support the idea that Pluto's orbit is affected by Neptune's gravitational pull.
Neptune was predicted by astronomers be observing the effects of its gravity. Neptune was discovered in 1846 by Johann Gottfried Galle.
Neptune
Astronomers predicted the existence and orbit of Neptune based on discrepancies in the orbit of Uranus. These discrepancies suggested the gravitational influence of another planet beyond Uranus, leading to the discovery of Neptune in 1846.
Astronomers used observational and mathematical skills to discover Neptune. They observed irregularities in the orbit of Uranus and calculated the gravitational influence needed to explain these irregularities, leading them to predict and discover the existence of Neptune.

Astronomers knew that Neptune existed before they could see it because they observed that the other planets orbited the sun in a way that could only be explained if they were being influenced by the gravity of another object of such mass. So the astronomers contemplated that there must be another planet somewhere that was changing the orbits of other planets. That planet is today called Neptune.

The 8th planet : Neptune.
Astronomers now realize that Pluto does not have nearly enough mass to noticeably affect the orbits of Uranus or Neptune.

Neptune
The god of oceans and seas.
Astronomers believe Triton may have been a planet that was captured by Neptune because it orbits in the opposite direction of Neptune's rotation and is tilted compared to the planet's other moons. This suggests it did not form in place with the other moons of Neptune, but rather was captured later in the planet's history.
