Better start actually looking then.

Well, other planets were discovered after seeing a disturbance in the force.

Only problem is the kooks and loons will see it as planet x on the rampage again and the Mayans were correct......

'But the recent discovery of a planet-forming disk of dust and gas more than 100 astronomical units (AU) from the star HL Tauri suggests planets can form long distances away from the centre of a solar system.'

Or suggests that they can't...

i think that loosely translates as

"We're running low and need new research funding, so here's a paper with clickbait as the title"

How refreshingly cynical.

I'm not saying it's Nibiru, but...

Seriously though, could something "Super Earth" exist that far out, based on our models of how we think the Solar System formed? If not, could there be captured objects from earlier systems, or maybe even something like a brown dwarf?

[jmorgan]

I suppose it is the remains of the protoplanetary disk.
