There has never been a 10th planet in our solar system, Pluto has been re classed as a sub planet because studies have shown that it was a giant asteroid from the kupier belt, there for never an original planet. Also if you are including the sun as one of the planets to make it 10, the sun is a star and not a planet.
Actually, Pluto is definitely not the last planet in the solar system. Pluto is the tenth planet, out of 18 planets and two protoplanets, and is binary, partnered with Charon. It is preceded by Orcus, and proceeded by Haumea.For a complete list of common objects in the solar system, see related links.
That is ERIS.Now it's classed as a dwarf planet, like Pluto. So, there are now just 8 planets.
The planet "Pluto" was recently reclassified as a dwarf planet because astronomers believed that it was too small to be classified as a "regulation" planet. The original images of Pluto made it look like a full size planet, but later observations revealed that it was about a tenth of the size that we first thought and that it had an orbit that can only be described as "wacky".
It was not so much a discovery that Pluto wasn't a planet, so much as a general concensus that it shouldn't be called a planet anymore. Over the past decade, astronomers have discovered several bodies beyond the orbit of Pluto that are in fact larger (for example, Eris.) They realized that there were probably many more they hadn't discovered yet and that the term planet was impractical for Pluto since it was so small and there were so many similar sized objects orbiting the Solar System. Eris was probably the final blow to Pluto's status. It is larger than Pluto and for a long time astronomers called it the solar system's "tenth planet''. In the face of this discovery and the fact that many other similarly sized objects had been found, the International Astronomical Union decided to formally define the word "planet" for the first time in 2006 and in the process effectively demoted Pluto.
There is not a 10th plane, yet. Some day maybe there will be but for now there isn't. Dont worry about this right now. There isn't even a 9th planet, but there used to be until scientists and astronauts called Pluto not a planet for its size and many other reasons. :) Maybe the 9th or 10th planet will be a livable planet and everyone can move there. Who knows. ;)
Pluto is the tenth planet in our solar system also the last!
As of right now, there is no tenth planet in our solar system. There are only 8, as Pluto is no longer considered a planet.
Currently, there are only eight planets in our solar system, so there is no tenth planet. The tenth planet ever to be discovered (not counting Pluto as a planet) is a planet that orbits the star PSR B1257+12. It is about a thousand light years away from the sun.
"Planet X" was originally a term for a hypothetical TENTH planet, BEYOND Pluto. Also, Pluto is no longer considered a planet.
there are millions of billions of trillions of planets, but there are no more than eight (pluto is a dwarf Planet) in our solar system.
A number of names for the "tenth planet" were discussed; two popular ones were Xena, from the TV program, and Persephone, in Greek mythology the consort of Pluto. However, in 2006, the International Astronomical Union recategorized Pluto as a "dwarf planet", and the body tentatively named "Xena" was officially named Eris as another "dwarf planet". (There are three other named "dwarf planets" to go with Pluto and Eris.)
There are only 8 major planets in the solar system, since Pluto (the old ninth planet) was re classified as a dwarf planet. If we did count the 5 additional dwarf planets, then Pluto would be the tenth one out, since there is a dwarf planet called Ceres between Mars and Jupiter.

If you count a dwarf planet, then yes: Eris was discovered in 2003 (but not identified until 2005). It is currently three times further from the sun than Pluto. Eris is larger than Pluto, and before the term "dwarf planet" was officially adopted in 2006, it was suggested that Eris had to be considered the solar system's tenth planet. If you don't count dwarf planets, then we actually lost a planet since the year 2000: In 2006, Pluto was downgraded from a planet to a "dwarf planet". In the year 2000 our solar system officially had nine planets, now it has eight. But it has three dwarf planets (Eris, Pluto, and Ceres).
There are only 8 planets in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto Used to be the 9th planet, but, it is now considered a Dwarf planet, more like a big moon than a real planet. There is no 10th planet in the solar system. There never was a 10th planet in the solar system.
