It's said to be the day of reckoning - but will the Blood Moon prophecy and an asteroid strike end the world as predicted?
Conspiracy theorists are predicting a cataclysmic event which will destroy civilisation - because of the looming blood moon and a prophesied meteor strike.
End-of-time cranks on various blogs and websites have come up with the period between September 22-28 as the likely time frame for the impending catastrophe.
On September 28th we will see the moon turn an incredible blood colour - and some think the end of days will arrive with it.
However, Gemma Lavender, features editor for All About Space magazine, urges calm.
She told the Liverpool Echo: “There are claims that, with the moon getting closer to Earth, that there is an increased risk of events such as earthquakes and volcanic eruptions - this is false."
“With the moon being closer to us than usual, and provided you have a clear night, observers should take advantage of the moon’s stunning lunar seas along with its beautiful craters and mountains, which can be observed with binoculars or a telescope," she continued.
Many biblical theorists maintain the event will trigger the Rapture and the start of a seven-year-tribulation.
These theories, which are restricted to tiny minority of churches and groups, have been dismissed by scientists and are thought to be well wide of the mark.
Fortunately for us, almost all asteroids are destroyed due to the extreme atmospheric friction heating they receive, breaking up into harmless shards that burn up before hitting the ground.
NASA has made asteroid detection a high priority.
A spokesperson said: "NASA knows of no asteroid or comet currently on a collision course with Earth, so the probability of a major collision is quite small.
"In fact, as best as we can tell, no large object is likely to strike the Earth any time in the next several hundred years."
