Of course, but we can't call 'em "plantes" any more. Because all objects we'll find will be classified only as dwarf planets. Tehre are no bigger ones any more in our solar system. If so, we'd already know that.
But, as a matter of fact, there are trillions of millions of planets out there in the universe ... were just about to discover the first giant ones ... don't yet have the technique to discover planets of the size of earth ...

We've discovered hundreds of Jovian (Jupiter-like) planets out there by observing the gravitational pull of the planet on its nearby star.
We should expect to find Terrestrial (Earth-like) planets in the near future by watching the planet "Transit" across the star, making it slightly dimmer for a period of time.
In our own solar system the chance of finding a planet has "ran out of gas" with the end of the gas giants (pun intended, omg so funny). But we will always continue to discover objects that orbit the sun, there are countless objects attracted to that life giver :P.

Yeppers! They've found several solar systems so far, including one with several stars and a planet larger than Jupiter circling its sun in roughly the same distance mercury orbits our sun. Considering there's over a billion galaxies and over a billion (possibly a trillion) stars each, there's bound to be planets somewhere. Especially ones with life. I seriously doubt we're the only ones out there. It's rather arrogant of humans to presume we're the only life in the universe! They've just caught the formation of two or three solar systems in the Orion Nebula. You can see several bright disks forming around new born stars. I find that quite an exciting event as all astronomers' ideas have been based on presumptions and hard to prove facts since their subjects are hard to study up close.
In our own solar system they've found several planet like balls of ice. That's what Pluto is classed as - a dwarf planet, and there's as many as 50 of them in our solar system. One of them, nick named Xena, is actually bigger than Pluto.

Not in our solar system... planets cannot form much further away than Neptune... if there was one we haven't seen yet something dramatic would have had to have happened to it to take it so far from the sun.
There are many, many planets outside of our solar system though that have all sorts of unusual properties. You can do a search on wikipedia or google or yahoo for "extrasolar planets" and find great information on them and the sneaky ways we find them. My favorite is HD 209458b, its atmosphere is heated so much that it is blowing off of it like a comet tail!

Of course there are more planets- many more, in fact. I think what you are asking is: are there any more inhabitable planets. And no one really knows the answer to that until we either receive first contact, or a signal from another life form.

Ya!Their r more planets in our solar system
Recently nasa's report says that they have found 5 more planets.One of them is sedna.and more.U know Now a days report says Pluto is not a planet.Because they said they new founded creations including Pluto and sedna r not planets.They should be some particals that all.So now history and text books changed to eight Planets theory.
But other then Solar system their r large number of suns and planets.So their is infinte number of planets.

After a long long time recently three more were consider to make them planets .later all these were removed .Whwt to talk of it Oldest Neptune which weasd a planet is now even deleted now .
If that is the situation who will think even locating one more planet .

Yes. Even one between Mars and Jupiter called Ceres.

Its called a 'dwarf-planet' but is such a large asteroid that it is round like planets as its gravity formed it that way.

In our solar system? Possibly, but probably not, unless they change the definition of a planet again. In other solar systems? Definitely.
