Some scientists have suggested that a big undiscovered body lying on the far outer reaches of the solar system could be responsible for many of the
mass extinction events throughout Earth's history, by shaking up the distant comet repository known as the Oort Cloud and sending some its denizens
screaming toward our planet.
But Planet Nine — a newly proposed but not yet confirmed world perhaps 10 times more massive than Earth that's thought to orbit far beyond Pluto —
probably could not have triggered such "death from the skies" events, researchers said. [Evidence Mounts for Existence of 'Planet X' (Video)]
"I suspect it has something like zero effect on us," said Mike Brown of the California Institute of Technology (Caltech) in Pasadena.
Brown and lead author Konstantin Batygin, also of Caltech, suggested the existence of Planet Nine in a paper that was published last week. They infer
the planet's presence based on indirect evidence: Computer models suggest that a distant, unseen world has shaped the strange orbits of a number of
small objects in the Kuiper Belt, the ring of icy bodies beyond Neptune.
Researchers say an anomaly in the orbits of distant Kuiper Belt objects points to the existence of an unknown planet orbiting the sun. Here's what we
know of this potential "Planet Nine."

Planet Nine likely has an elliptical orbit, coming within 200 to 300 astronomical units (AU) of the sun at its closest approach and getting as far
away as 600 to 1,200 AU, Brown said. (One AU is the distance from Earth to the sun — about 93 million miles, or 150 million kilometers).
Neptune orbits about 30 AU from the sun, and Pluto never gets farther than 49 AU from our star. So Planet Nine, if it exists, is very distant indeed
— but not distant enough, Brown said, to stir up any of the trillions of comets in the Oort Cloud, which begins perhaps 5,000 AU from the sun.
The existence of such a "perturber" has been hypothesized as a way to explain the mysterious periodicity of big extinction events on Earth, which have
recurred roughly every 27 million years over the last quarter-billion years or so.
"Really big planets really far away could do that," Brown told Space.com. "Planet Nine is smaller than all these things that people have called
'Planet X' — that's always been sort of Jupiter-sized, or even brown dwarf-sized, or something. This is a good bit smaller, and a good bit closer;
it's not in the realm of the comets."
The putative Planet Nine also completes one orbit every 10,000 years or so, he added.
"That sounds like a long time, but it's a pretty short orbit," Brown said. "If it were doing this thing every time it went around the sun, it would've
been doing a lot of it, and I don't think there's anything going on like that
Theirs that ^^^^^^^^^^^^^^^^^^^^^^^^
But i just don't trust the MSM. Has anyone ever timed each mass die off or event and seen if there is a certain amount of time between them? Just
curious
