Though Lieder herself has not specified a new date for the object's return, many groups have taken up her idea and cited their own dates. One frequently cited date was December 21, 2012. This date had many apocalyptic associations, as it was the end of a cycle (baktun) in the long count in the Mayan calendar. Several writers published books connecting the encounter with 2012
Despite that date having passed, many websites still contend that Nibiru/Planet X is en route to Earth
In 2012, Lieder claimed that U.S. President Barack Obama futilely attempted to announce the presence of Nibiru near the sun.[28] After 2012, she claimed that several world leaders had intended to announce the presence of Nibiru near the sun on October 20, 2014. Two weeks after the supposed date of announcement, she claimed that it did not occur because of consternation amongst the establishment.
