Possible "extra" planet discovered in our solar system?

[Parsons]

I hate you Austin... You beat me to it. This certainly is the biggest astronomical finding in my lifetime so far.

This is 100% legitimate (in the main stream) and not any kind of 'quackery'. One of the two scientists that found this is the guy who is directly responsible for declassifying Pluto as a planet. So he is extremely prominent in the astronomical community. Also, it has been peer reviewed in the Astronomical Journal.

Batygin and Brown inferred its presence from the peculiar clustering of six previously known objects that orbit beyond Neptune. They say there’s only a 0.007% chance, or about one in 15,000, that the clustering could be a coincidence.

They state that it won't be "confirmed" until they find it in a telescope. But even if they do manage to find it with an earth based telescope / the Hubble, it's just going to look like a blurry dot. Previous to the New Horizons spacecraft, the best photo of Pluto was just an extremely fuzzy white dot:



The closest orbit of Pluto is 30 AU (1 AU is the distance between the Earth and the Sun). The closest orbit of this planet is 200 AU and is estimated to range out to 1200 AU. So I highly doubt we will get a photo of this planet even remotely as good as the one of Pluto pre-New Horizons.
