The controversial theory of the Twelfth Planet claims the existence of a massive celestial body, Nibiru, that orbits the Sun in a highly elliptical path. Unlike the planets in our solar system, which follow relatively circular orbits, Nibiru's trajectory is said to be elongated, bringing it closer to the Sun at its perihelion and farther away at its aphelion Nibiru's orbital period is approximately 3,600 years. This means that the planet returns to the inner solar system every 3,600 years, potentially coming dangerously close to Earth. Sitchin suggests that these close encounters have been responsible for cataclysmic events throughout Earth's history, such as the Great Flood mentioned in various ancient mythologies.One of the primary pieces of evidence to support the existence of Nibiru is the ancient Sumerian texts. these texts contain coded references to the planet and its inhabitants, the Anunnaki. the Sumerians had a deep understanding of astronomy and celestial mechanics, and that they recorded their observations in a symbolic language that has been misinterpreted by modern scholars.In addition to ancient texts, some proponents of the Nibiru theory point to astronomical anomalies as evidence of the planet's existence. For example, they argue that the sudden appearance of the planet Venus in ancient records is a sign that Nibiru had passed through the inner solar system, perturbing the orbits of other celestial bodies.The controversial theory of the Twelfth Planet claims the existence of a massive celestial body, Nibiru, that orbits the Sun in a highly elliptical path.
