'Planet of the Crossing.' The Assyrians and Babylonians called it 'Marduk', after their chief god. Sumerians said one year on planet Nibiru, a sar, was equivalent in time to 3,600 Earth years. Anunnaki lifespans were 120 sars which is 120 x 3,600 or 432,000 years. According to the King List - 120 sars had passed from the time the Anunnaki arrived on Earth to the time of the Great Flood.
