Next Thursday, the asteroid known as 2012 T4C will pass between the moon and the Earth at a breathtakingly close distance of just 4,200 miles from our planet.
The asteroid could be up to 30 metres in size, and it is one of the closest ever flybys.
However, Christian conspiracy theorists believe that the asteroid’s arrival will mark the beginning of the end of the world.
A blog ran by poet Mel Brake says the passing of the asteroid will be a sign in the sky that Mother Mary is to return and the apocalypse will begin.
Friday 13 APOCALYPSE WARNING: Asteroid flyby will ‘mark the return of Mother Mary’
The website says that October will mark the 100 year anniversary of ‘Our Lady of Fatima’.
In 1917, between May and October, three young Portuguese shepherds were said to have been visited by Mother Mary who provided them with visions of the apocalypse.
Now, a century on, some believe that the asteroid is the final sign.
The flight path of 2012 T4C
Mr Brake’s blog points to Revelation 12:1 which says that a “sign” will appear in the heavens before a woman comes and provides great anguish to those on Earth – the woman being Mother Mary in this instance.
The Bible passage 12:1–2 reads: “And a great sign appeared in heaven: a woman clothed with the sun, with the moon under her feet, and on her head a crown of 12 stars. She was pregnant and was crying out in birth pains and the agony of giving birth.”
The blog post reads: “The message is clear have we a choice between light or dark, and since 100 years of Mother Mary’s appearance to the three little children of Fatima.
“When the Woman Clothed in The Sun returns in October 13, 2017 what will she return as a crying and sorrowful Mother or a loving and happy Mother because we her children have embraced her gift of love: The Fatima Gift.”
Nasa however says that there is no danger of the world ending and will use the flyby – less than the 5,400 miles between London and Los Angeles – to gather valuable data on the asteroid which was discovered in 2012.
Is the End of the world coming?
Michael Kelley, program scientist and NASA Headquarters lead for the TC4 observation campaign, said: “Scientists have always appreciated knowing when an asteroid will make a close approach to and safely pass the Earth because they can make preparations to collect data to characterise and learn as much as possible about it.
“This time we are adding in another layer of effort, using this asteroid flyby to test the worldwide asteroid detection and tracking network, assessing our capability to work together in response to finding a potential real asteroid threat.”
It is the second time in as many months that someone has predicted the end of the world.
In September, Christian numerologist David Meade believed that September 23 would see the arrival of the mythical planet Nibiru, which he thought would bring in the apocalypse.
Mr Meade reached this conclusion by analysing the same passage in the Bible.
Mr Meade said: “The great sign of The Woman as described in revelation 12:1-2 forms and lasts for only a few hours. According to computer generated astronomical models, this sign has never before occurred in human history.
“It will occur once on September 23, 2017. It will never occur again. When it occurs, it places the Earth immediately before the time of the Sixth Seal of Revelation.
“During this time frame on September 23, 2017, the moon appears under the feet of the Constellation Virgo. The Sun appears to precisely clothe Virgo.”
However, September 23 came and went without any credible sightings of a large planet that would cause the end of the world.
