You mean 5 times the MASS of Earth and not the size, we can’t speculate the size as the object haven’t been photographed yet, we can speculate the mass due the gravitational pull of the eventual planet in Kuiper Belt Objects, SIZE is totally DIFFERENT of MASS.

Hello, could you add Spanish or CC subtitles to be able to translate the information? Thank you.

New details? New speculation you mean. Details suggest theyve seen or found something.

Could have been explained a bit clearer in places. Nice tattoo, though (don't dare show the non-tattooed arm....that is, if it trimmed checked shirt. The complete hipster package.
