Is there or is there not a 9th planet? Scientists have been meticulously investigating this question for more than 20 years. Once Pluto was the 9th planet of the solar system.

But after its demotion to a dwarf planet, we officially have only 8 major planets left in the system.

That at the outermost edge of the solar system another planet must be, calculated researchers on the basis the orbits of objects of the Kuiper belt. Nobody has seen the 9th planet, which should have a stately size, so far.

There were or are however legends around a mysterious further planet, which raises only every few thousand years and then brings evil over the world.
