We know because astronaughts have gone to space and exploured around space and found out many more plantets beyond pluto.

Why did astronomers begin searching for a planet X?
Errors in the calculations of Neptune's mass led scientists to believe that there was another planet affecting Uranus' orbit. Scientist proceeded to dub this planet Planet X.
In the 1800s why did astronomers predict that the planet neptune would be discovered well before anyone had seen it?
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.
What planet do astronomers believe that there is a good chance of liquid water?
Mars scientists found water on. Mars
Why did early astronomers think that mercury was two separate planets?
early astronomers thought that Mercury was a seprate planet to another because it was so small
What evidence led scientists to believe Neptune existed before they ever saw it?
Unexpected changes in the orbit of Uranus led astronomers to believe that there was another planet affecting its orbit. Detailed studies of Uranus's orbit allowed them to predict its existence and location.
What planet do astronomers believe there is life?
Earth

What planet were scientist studying when they found neptune?
Astronomers were actually studying another planet, Uranus.
Is the lost planet found?
There is no such thing as a lost planet. Astronomers haven't seen another planet from somewhere else yet.
Is there another planet beyond Pluto?
No, but there is a dwarf planet including pluto.
Besides Earth astronomers believe they are most likely to find evidence of life on what planet?
Mars
Explain about planet X?
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.
What planet some astronomers don't think is a planet?
Astronomers have decided that Pluto does not meet the definition of a planet.
Why is pluto the ninth planet?
It is no longer classified as a planet as astronomers now believe its a asteroid that got pulled into an orbit with our sun. Some also believe it to be a misplaced moon of Neptune.
Is there another planet beyond Uranus?
Yes. Neptune orbits beyond Uranus.

Why do scientist believe there used to be another planet in between Mars and Jupiter?
This was because the orbits of those planets suggested there was something pulling in the direction of the belt. When astronomers looked there, they did not find a planet, but instead a collection of asteroids. It was these that were pulling on the planets.
