Nibiru (also transliterated Neberu, Nebiru) is a term in the Akkadian language, translating to “crossing” or “point of transition”, especially of rivers, i.e. river crossings or ferry-boats. In Babylonian astronomy, nibiru (in cuneiform spelled dné-bé-ru or MULni-bi-rum) is a term of the highest point of the ecliptic, i.e. the point of summer solstice, and its associated constellation. The establishment of the nibiru point is described in tablet 5 of the creation epic Enûma Eliš”
