Nasa thinks there may be a hidden ‘Planet 9’ lurking in our Solar System – here’s why
NASA is looking out for definitive proof that the fabled 'Planet 9' could be hiding in the far reaches of our solar system.The legendary planet, nicknamed X, is hypothesized by NASA to be ten times as large as the Earth and operating on a humongous orbit.It's thought that should the planet exist, it would orbit about 20 times farther from the Sun on average than Neptune meaning it could take may take 20,000 years to make one full orbit around the Sun.Planet X was first being talked up as a possibility when Caltech researchers proved that its existence was mathematically possible. in 2015.The search for a new planet came about after scientists searched for an answer as to the peculiar orbits of some smaller objects in the Kuiper Belt, a distant region of icy debris that extends far beyond the orbit of Neptune.
