From its discovery in 1930 until its degradation in 2006 Pluto was considered the solar system's ninth planet. Now it is considered a dwarf planet, and one of 5 official dwarf planets.

Is there a new planet in your solar system?
No, there are no new planets in our solar system. They have all been here for a long time! Our solar system has eight planets, since Pluto was downgraded to a dwarf planet. There are some new dwarf planets: Eris, Ceres, and the newest MakeMake. There are about a dozen more candidates for dwarf planet status. Pluto, Eris, and MakeMake are also considered plutiods, which means they are beyond Neptune's orbit. See Related Links below for more information.
What do all planets in the solar system revolve around?
The Sun. There are 8 bodies classified as planets, and as of 2009 there are 5 classed as dwarf planets. There are many more objects with long orbits past that of Pluto, and these are being studied and classified.
Is Pluto a planet or a star?
There is some debate among astronomers whether Pluto is a planet (vs. an asteroid or some such), but it is definitely not a star.[EDIT] (from a completely different guy :P)Pluto is not considered a planet nor a star. A planet can be defined as:- An object orbiting around the sun(CHECK)- Needs enough gravitational force to pull itself into a spherical shape (CHECK)- Needs it's own orbit with no other object on it's orbit(BUMMER :P)As long as an object in the solar system does not meet the third point (but meets the other two points), it is considered a 'dwarf planet'...FYI (for your info):There are other objects (or dwarf planets) in Pluto's orbit (like: Eris, Sedna, Orcus...), so as long as Pluto does not crush into all of them and add up it's mass, it won't be considered a 'planet'. In other words, Pluto may be a planet sometimein the future.By: Animefanrarr
How is Pluto different from gas planets?
Pluto is closer in size and composition to the MOONS of the outer planets Neptune and Uranus. It is not as substantial as the inner terrestrial planets, but is typical of many icy objects that orbit past Neptune. The gas giants are massive objects with deep, dense atmospheres. Pluto is so small it cannot hold much of an atmosphere at all.
What planets switch places in planet order?
No normal planets actually switch orbits the way that Janus and Epimethius (Saturn moons) do in a co-orbit. Some Dwarf Planets sometimes are closer or farther from the sun than other kindred Dwarf Planets depending on their locations along their orbits. Pluto is sometimes closer to the sun than Neptune. Haumea is usually further from the sun than Pluto but sometimes is closer. Makemake has the same relationship with Haumea. Eris is usually the farthest but sometimes in its elliptical orbit is closer to the sun than Haumea.
What is the proximity of Pluto to the other planets?
Pluto is no longer a planet. It is considered a dwarf planet or Kuiper Belt Object. The closest planet to it is Neptune and that is a long way off.
Is Pluto in the solar system?
Yes and no. It was decided on August 24, 2006 that Pluto be classified a dwarf planet. Because dwarf planets are a subclassification of planet, it would be accurate to call Pluto a planet, in a general setting (bearing in mind, though, that there are 10+ other dwarf planets in our solar system, some larger than Pluto).
Is there a new planet in your solar system?

Does Pluto revolve on its side?
Yes. It revolves around the sun and has a long period of revolution.
What number planet away from the sun is Pluto?
I do not really understand what you are asking but The Dwarf Planet Pluto is the ninth planet from the sun, it is believed that it is not even a planet anymore. Thank you for using wikianswers.com.
When did Kepler find Pluto?
Neither Johannes Kepler nor the Kepler Space Telescope discovered Pluto. Pluto was discovered by Clyde Tombaugh in 1930, long after Johannes Kepler died and long before the Kepler telescope was created. The Kepler telescope was built to discover planets in other solar systems, not our own.
Which is the coolest planet of the nine planets?
there are only 8 true lanets meaning that Neptune is the coldet but pluto is a dwarf planet but he is colder still. Edit by Dan: Just thought I'd point out that Pluto isn't a planet not only because of it's size but because it was too far away from the other planets and they kept discovering more planets and it would be okay just as long as they didn't find anything bigger than Pluto which they did which was the planet Eris;D so now Pluto belongs to the very distant Kuiper Belt:)
Why is Pluto excluded as a planet?
Because it was too small and it seemed to be following some other orbit rather than our sun. Its orbit was off from ours by too much time. It was faster than it should have been. ______________ I considered editing the question, but left it because it might resonate with some popular misconceptions. Pluto is still out there, and our struggles to categorize it have not diminished it one bit. It remains part of our solar system and will remain so as long as the solar system exists, barring some unforeseen disaster. It will continue to be a fascinating and inspiring object and one worth studying. Neither its size nor the speed of Pluto's orbit are factors in Pluto's categorization, although many point out that the region that far out in the solar system seems not to be the right place for a planet so small. That part of the solar system is where the gas giants live, and the smaller more rocky planets live near us. Pluto is simply no longer considered a major planet. It is a minor planet. In order for a body to be considered a planet it must orbit a sun or the remnant of a sun. Pluto does that. It must be large enough so that by force of its own gravity it has formed itself into a sphere-like shape. [Planets are not perfect spheres.] Pluto has done that too. So far so good. It must also have cleared its neighborhood of debris. No planet has done this completely; there are chunks of rock and tons of dust and ice floating around. But the major planets have no objects in the vicinity of their orbits large enough to challenge their primacy in their orbits. Here is where Pluto runs into trouble. Pluto's orbit is roughly 248 earth years. During that time Pluto spends roughly 12-14 years in the part of its orbit that takes it closer to the sun than Neptune, the outermost major planet. The rest of the time it is in what is called the Kuiper Belt, a region beyond Neptune that is filled with icy chunks, some of them rivaling the size of Pluto. Probably many of the comets that we sometimes observe spend most of their time there. In fact, Pluto may be very much like a large comet, and might act like one if it got close enough to the sun. It is all the time that Pluto spends among the many other objects in the Kuiper Belt that disqualifies it from being a major planet. Often, Pluto is referred to as a Kuiper Object. So Pluto fans, do not despair. Pluto is in reality eveything it ever was. We just don't include it on the list of major planets any more.
Where does Pluto reside?
Pluto is the smallest of all known Planets. Now it is considered to be a "dwarf planet". It takes 248 years to make one orbit around the sun. As to where it is, depends on time. Earth and Pluto move in different orbits, so to detect where Pluto is, requires an exact time.
Is Pluto a planet or a star?

How large does an island have to be to be considered major?
An island is generally considered major if it is larger than 100,000 square kilometers in size. Islands of this magnitude often have significant influence in terms of population, economy, and geopolitical factors.
