What do you define as a planet though? If you consider our sun a frame of reference, you might find that technically some far away objects bigger than the sun have complex periodical movements around the sun.
Noob question: Why isn't it passing in front of stars? Are we seeing a sequential dimming of occluded stars along the plane of the ecliptic?
My intuition suggests that a planet far out and small would be very difficult to detect by its occlusion. This page calculates that Pluto for instance spans only 3 pixels at the Hubble space telescopes resolution: http://www.planetary.org/blogs/emily-lakdawalla/2013/0214101...

"Pluto Two!? That's ridiculous!"
"Wait, is it two like the number two or too like also??"

I don't know how our story resolves, but that exchange popped in to my head.

A nice update in the search for Planet Nine that touches on a lot of new computational, survey-based, and modeling efforts to localize the planet. Great level of detail.
