The planet NIBIRU revolves around Nemesis, a dark subdwarf star more massive than Jupiter.
Nemesis nears our Sun, at the KUIPER BELT, 48 Astronomical Units from Earth, every 10,800 Earth years.
Nibiru circles Nemesis but did not orbit our sun. Instead, every 3,600 years Nibiru passed though our inner solar system between Jupiter and Mars.
One of Nibiru’s years (the time Nibiru took to circle Nemesis) was thus 3,600 Earth years--long enough for 180 generations of Homo Sapiens Earthlings to live and die.
Nibiru stabilized into a clockwise 3,600-year orbit. But in 10,900 B.C., Uranus drifted away from the Sun and sped Nibiru toward Earth sooner than 3,600 years. As Nibiru flew by, Uranus caught Miranda, a moon of Nibiru. Miranda, now a moon of Uranus, circled it instead of Nibiru. From 10,000 B.C. on Uranus slowed Nibiru’s orbit to 3450 Earth years rather than 3600.
Nibiru returned to perigee in 7450, 4000, and 556 B.C. and next returns to the inner solar system in 2900 A.D. rather than 2012 as it would on its earlier 3600-year orbit (though the debris 180 degrees from Nibiru on Nibiru’s orbital path, its far LAGRANGE POINT moving in harmonic procession always opposite Nibiru, is upon us now).
