Here is a brief description of thy they do not think this object is a super-earth or any kind of planet at all:
One of the objects was found to be near W Aquilae in the night sky—the other adjacent to Alpha Centauri . Both groups report being skeptical at first regarding a faint glow, but monitored what they had seen nonetheless—to their surprise they found that the objects appeared to move relative to the stars behind them, which suggested they might be relatively close and that they might be orbiting the sun.
Both teams think it could be an ordinary star or just an illusion. And some think it could be a random blip of noise that they detected. What does that even mean a random blip of noise from where? Earth? A neutron star?
Check back for futher updates as it is clearly too early to rule anything out either way!

Niribu?
Won’t do much good out there
Doesn’t surprise me.
Sounds cold…..
You must be kidding. Have you ever thought about the temperature out there.
Would not surprise me if we discover that we are part of a binary star system with the other star hosting planets as well. This is very common throughout our known galaxy.
This planet, and it’s interactions with our solar system and the effects it has on this planet, has been written about in many ancient texts.
Why not? They’ve been here. Gilgamesh.
