The 12th Planet

*The 12th Planet*, a book by Zecharia Sitchin, proposes that an additional, distant planet called Nibiru exists beyond Neptune. Sitchin suggests that Nibiru's gravitational influence has affected the solar system and that ancient civilizations were aware of it. He claims that this planet’s inhabitants, called the Anunnaki, interacted with early humans, possibly influencing their development and myths. However, mainstream scientists and astronomers have found no evidence of such a planet, and Sitchin's theories are widely regarded as pseudoscience, lacking support from planetary science and astronomy.
