(In the Sumerian texts, the Annunaki are not depicted as alien space gods in flying machines who crossed their DNA with Homo erectus to create mankind for the purpose of using us as slaves to mine gold for them. Also Nibiru was seen every year which demolishes Sitchin's view of a 3,600 year cycle for it to pass around the sun, and it wasn't a planet located pass Pluto.) FULL STORY at above link.
"A planet with an orbit so eccentric that it took 3,600 years to orbit the sun would create instabilities inside our 4.5-billion-year-old solar system. After only a few trips, its gravity would have significantly disrupted the other planets, whose own gravitational pushes would have changed the hypothetical world's orbit significantly." FULL STORY at above link.
"It simply isn’t possible to have an orbit that would keep a Planet X behind the Sun as seen from Earth, and also allow it to encounter the Earth every 3600 years (or ever).""Because the Earth moves around the Sun on its orbit, the only way to keep another planet permanently behind the Sun as seen from Earth is for it to orbit the Sun in the same amount of time as the Earth, that is, one year. If it had any other orbital period, it would be visible away from the Sun for long periods of time, like the other planets in our solar system. If Planet X had a circular orbit with a period of one year, it could always be exactly behind the Sun as viewed from the Earth–but this would mean that it could never come close enough to the Earth for a close encounter!"
