The first "discovery" of this planet/brown dwarf dates back to 1983. There is little doubt these days scientifically as to it's existence, but as to it's location, that's another matter. I have wondered why all of the super-cooled telescopes (like the Vatican operated LUCIFER telescope on Mt. Graham in Arizona) have been built, including at least two currently in orbit via NASA. These telescopes are designed to find interstellar bodies that emit little to no hear and light. Which would seem to contradict some of the pics we've seen on the internet of Planet X (sometimes referred to as Nibiru). Whatever the case, here's a collection of evidence gathered over the last two years.
