 Beginning in 1995, websites such as ZetaTalk have claimed that Nibiru or "Planet X" is a brown dwarf currently within our planetary system, soon to pass relatively close to Earth.Sitchin disagreed with the timing of passage.Sitchin also postulated that Pluto began life as Gaga, a satellite of Saturn which, due to perturbation caused by Nibiru's passing, was flung into orbit beyond Neptune.
