Recent evidence suggests that a massive body is lurking at the outskirts of our solar system, far beyond the orbits of the known giant planets. This object, at a distance approximately 20 times further than Neptune and with a mass approximately 5000 times larger that Pluto, is the real ninth planet of the solar system. I will talk about the observation that led us to the evidence for this Planet Nine and discuss how so massive an object could have been hiding in the outer solar system for so long. Finally I will discuss the international effort to pinpoint this newest member of our planetary family.
