There's Exciting New Evidence a Real Planet Nine Is Out There
Who needs Pluto?
DAVID NIELD 20 MAY 2018
Is there a ninth planet out there in our solar system, lurking out of sight of astronomers, far past the orbit of Pluto (the ex-ninth planet)? According to new observations of a strangely behaving rock in deep space, the answer just might be yes.
The new object we can see and observe is called 2015 BP519, and looks like it could be as big as a dwarf planet itself.
What's interesting is that the rock isn't on the same plane as the Solar System planets, which are all spread out like a disc it's at a 54-degree angle.
And one of the possible explanations for that rather crazy orbit is the existence of another planet, far beyond Neptune and around 10 times the mass of Earth. A planet that size would provide the necessarily pull to keep 2015 BP519 where it is.
