Nibiru

Nibiru (also known as Planet X, or Hercolubus) really exists and is not a myth.
(Myths are those fake photos of individuals who claim to have seen Nibiru with the naked eye. It is not visible to the naked eye from Earth, because it is still far away, and as it is a brown dwarf it reflects little light, it is only visible with an infrared telescope).

Continuing:
Nibiru is real, it was captured by Spanish astronomers, behind Pluto, and they named it "G1.9".
