The only new planet that I know of in our solar system is Xena (originally called Planet X), which is located just outside the orbit of Pluto (which I still consider a planet).

There are now only 8 Planets in our Solar System.The Planet
patent of Pluto was taken away by some real Nut Scientists.
Now all there are : Mercury,Venus,Earth,Mars,Jupiter,Saturn,Uranus,Neptune.
Hope this Satisfies your Curiosity!

Currently only eight objects around the sun which are officially called "planets"
Pluto has been dis-honoured from the 'planets' recently.

A team of astronomers have discovered two new planets outside the solar system, both of which are extremely close to their stars, indicating that they are the hottest ever found.
They revealed information about the new found planets at the Transiting Extrasolar Planets Workshop at the Max Planck Institute for Astronomy in Heidelberg, Germany.
Stephen Kane, an astronomer from the University of Florida who worked with more than three dozen astronomers on this project, said that they pinpointed the planets by detecting the slight dimming of starlight, which occurred when they passed in front of their stars.
He said that of about 200 planets discovered so far, the new planets are only the 13th and 14th to be found using this technique, called the transit method, adding that most planets outside our solar system have been found using the radial velocity method, which measures the gravitational wobble in the star induced by the orbiting planet.
"We can expect these two planets to be the first in a wave of a whole lot of these new types of planets," he said.
Known as 'Hot Jupiters' because of their Jupiter-like size and temperature, the new planets are so close to their stars that they complete their orbit in a mere two-and-one-half days, respectively, which is faster than the 88 days orbit of Mercury, the planet with the fastest orbit nearest the sun.
Kane said that the extreme closeness of the orbit also means that these planets are hotter than Mercury, which has a surface temperature of 752 degrees Fahrenheit. The temperature of the new planets is estimated to be at least 3,272 degrees.
There is also evidence that the solar radiation from the stars is so intense that it is whipping away their atmospheres.
"Hot Jupiters are assumed to have a significantly reduced lifetime due to their proximity to the star," Kane said.
Kane said that the work was done through UK's leading planet detection program, a consortium of eight universities called SuperWASP, or Wide Angle Search for Planets.
He said that they snapped photos of millions of stars in the southern and northern skies by using twin telescopes attached to high-end cameras, and then investigated them using computer programs to detect light curves from the stars.
"The astronomers surveyed millions of stars using twin telescopes snapping photos of the southern and northern skies from La Palma in Spain's Canary Islands and Sutherland, South Africa. Each telescope is equipped with eight wide-angle cameras, each of which has a field of view of eight degrees, which comprises a relatively large chunk of the sky. By comparison, the full moon comprises about half a degree," he said.
"We have computer programs which are able to search all of these light curves from the stars and see if there's something in them which looks like the star has become fainter for a short period, but it's a complicated task," he added.
After identifying the tiny dips in starlight, a French-built instrument detected a slight wobble in each star's motion as the planets passed around them, confirming the existence of the planets.
The planets are located in the constellations Andromeda and Delphinius, respectively.
The Andromeda planet is more than 1,000 light years away, while the Delphinius one is 500 light years away.
Kane said their discovery adds to growing knowledge about how planets form, which should help astronomers understand and zero in on Earth-like planets.
"Once we understand planet formation, we'll understand a lot more about how terrestrial planets form as well," he said. (ANI

There are no new planets.
It's that Pluto was eliminated.
