Researchers find evidence of ninth planet
Astronomers at the California Institute of Technology say they have found evidence of a giant planet tracing a bizarre, highly elongated orbit in our outer solar system. The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth, according to a statement from Caltech. Ref. USAToday.

Well, it completes a rotation every 10.000 years, so there is a possibility that we will see it maybe...once? As a species I mean. Plus, planets do not produce their own light and it is very difficult to find them by themselves, they need a background contrast to be detected visually.
Naah, the Solar system is stable. It has not happened in the last billion years and will not happen for the next couple of billion. It is more possible to get hit by a gamma ray burst rather than a celestial body (Large meteors excluded, but the gamma ray burst is still more plausible danger).
Its pretty stable but any of those asteroids circulating the outer ring could come our way. I hope interplanetary travel can happen sooner rather than later so we can really know what makes up our universe. Just imagine, if there is a 9th then there could be a 10th as well.
Planet Nine: A world that shouldn't exist
Earlier this year scientists presented evidence for Planet Nine, a Neptune-mass planet in an elliptical orbit 10 times farther from our Sun than Pluto. Since then theorists have puzzled over how this planet could end up in such a distant orbit. New research examines a number of scenarios and finds that most of them have low probabilities. Therefore, the presence of Planet Nine remains a bit of a mystery. Ref. Source 7z.
