Pluto is still in our solar system - it only got 'demoted' from true planet to dwarf (or minor) planet. After we discovered a bunch of new object something like Pluto, we had to decide if they would all be called planets, or we came up with a consistent definition which excluded them. The IAU decided in 2006 to reclassify - such that we have only 8 true planets. But Pluto is not forgotten.

Are there more planets that are not in the us solar system?
no there are not apart from Pluto that is no longer in our solar system
How may planets are in your solar system?
9 with Pluto but now Pluto is not a planet so 8 O_O but maybe more
What planet was taken away from the solar system?
Pluto is the only one that has been taken away from the solar system for now but more planets are beginning to be argued over. Pluto was taken out because it was a moon.
What solar system body was a planet but officially isn't any more?
Pluto and the dwarf planets
Why is Pluto no more considered in your solar system?
its not considered as a planet because it is cold an has one tempature
Why inst Pluto considered a planet any more?
Scientists think pluto is to small to be a real plantet compared to the ones in our solar system.
When was Pluto ruled out as planet from the list of planet in the solar system?
In 2006 Pluto was degraded to the status of dwarf planet(there is another dwarf planet, Eris, that is more massive than Pluto).
Why do some astronomers believe that there is another planet in your solar system beyond Pluto?
We know because astronaughts have gone to space and exploured around space and found out many more plantets beyond pluto.
Reason why the Pluto not belong into Solar System?
Pluto is still in our solar system, it is just not considered a planet anymore. Scientists looked more closely and decided that Pluto is not a planet based on four main reasons: 1. Pluto's tiny, tiny size 2. Pluto's orbit is not even close to being elliptical (a normal planet orbit) 3. Pluto's moon is about half of the planet's size and they both revolve around each other; moons are not supposed to be even close to 1/2 the size of the planet 4. Pluto is just outside a major icy comet belt in which those comets look quite similar to Pluto. Pluto is still somewhat considered a planet, it is just not considered one of the major planets anymore (Earth, Mars, Jupiter, Venus, etc.). It has been "demoted" to a dwarf planet.
What planet in your solar system do scientist know little about?
neptune and Pluto are the two planets (altho Pluto is not officially a planet any more) that we know the least about because they are the ferrets away in the solar system and there for get the least amount of attention. but apart from mars and venus we do not know that much more about the other planets.
Why do planet Pluto is not included anymore in the solar system?
It is part of the Solar System. The Solar System includes planets, moons, comets, asteroids, a star and dwarf planets like Pluto. It's just not a planet. It never was a planet (according to the new definition).A planet is a celestial body that (a) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (b) is in orbit around a star, and is neither a star nor a satellite of a planet."Pluto is no longer considered a planet because it does not fulfill the criteria, but Pluto never stopped being considered a part of the solar system. It still orbits the same star, although it is a very distant orbit.
Why was Pluto closer to the sun then Neptune?
because its orbit was highly eccentric and used to intercede the orbit of Neptune. that is why Pluto is no more a part of our solar system as it collided with Neptune and exploded.
