Ceres? Discovered in 1801 (so it's not newly discovered) it was the first of 4 asteroids that were accepted as planets for the first half of the 19th Century. But they were all booted out of the planetary club when more asteroids were discovered, It is not however by Pluto but lies between Mars and Jupiter.
Charon? Is right by Pluto. it is its largest moon (discovered 1978 so it is not new either)

Perhaps you're referring to 2003 UB313, an icy world discovered in 2003 and yet to be given an official name. Its discoverer, Mike Brown, nicknamed it Xena, but that will never be its official name.
It's a tad bit larger than Pluto, and roughly twice as far from the Sun as Pluto is. It has a moon, too, nicknamed Gabrielle. Again, that won't be its official name.
2003 UB313 is not a planet, although some people were refering to it as the 10th planet for a while. Its discovery and the discovery of others like it is partly what pushed the International Astronomical Union to finally define the word "planet". So now Pluto is no longer a planet, and neither is 2003 UB313.
Pluto and 2003 UB313 are considered the two largest known objects in the Kuiper Belt, which is analogous to the asteroid belt except made up of icy bodies instead of rocky bodies; that is, comets instead of asteroids. Other KBOs are Sedna, Quaoar, and quite a few others that don't have names yet. Here's an artists rendering of what they might look like:

We don't have any good images of any of them, as no space craft has ever been near any of them.

There is no new planet. In fact, there is one less planet than there was a few weeks ago (Pluto has been demoted to a dwarf planet).
I think you're talking about either Charon (Pluto's moon) or Ceres (the largest asteroid, now considered a dwarf planet, which orbits between Mars and Jupiter).
