Thanks for the post. I saw it right after you posted it. I read the article right away then got a bit irritated about the article. It would seem that Space.com is grasping for articles lately.
That's so old stuff it took me back a few years. lol
I used to believe in the rogue planet because it would account for the rather uniform Era's here on Earth.
The one argument against it that has swayed me over the years was it's probable mass. My favorite planet to watch is Jupiter.
I love to watch the moon's. The other thing I find amazing about it is it's inferred glow. Because of it's mass, Jupiter emits more heat than it absorbs.
The article states the planet would be very cold. But to double the mass of Jupiter would be to double it's heat output. There's an unknown point where the mass of a planet expells enough heat to blow away it's gases and a point where the gravity holds those gases to the planet and heats up to finally ignite into a brown dwarf. Either way a planet twice the size of Jupiter, at 1 light year, would stand out like a beacon in inferred if not visable light.
