by There are eight known planets in the solar system (ever since Pluto was booted from the club), but for a while, there has been some evidence that there might be one more.
A hypothetical Planet 9 lurking on the outer edge of our solar system.
So far, this world has eluded discovery, but a new study has pinned down where it should be.
The evidence for Planet 9 comes from its gravitational pull on other bodies.
If the planet exists, its gravity will affect the orbits of other planets.
