Some believers claim the alien world – also known as Planet X – has appeared.
But Nibiru is yet to be officially confirmed – leading some doubters to question Mr Meade’s prophecy.
Mr Meade said Planet X is still “between Mars and Earth” – but it is “very close”.
And he has now revised his prediction to say it will appear between November 20 and December 20.
In his first interview since the September 23 prophecy date passed, Mr Meade said working out exact dates from the book of Revelation is complex and doesn’t describe a clear timeline of events.
Mr Meade said Planet X will appear 30 to 60 days after this – which puts it between November 20 and December 20.
“It is there, it is very close.
“I think it is going to appear in the first 30 to 60 days of the opening of the sixth seal at the beginning of Tribulation period.”
UFO expert Nick Pope has mocked Mr Meade’s prediction after Nibiru failed to appear.
Space boffin Dr Brian Cox has also insisted Planet X doesn’t exist.
