The final blood moon of the ongoing tetrad will take place on 28 September. So, will the world come to an end on the day, as rumoured? Will asteroids strike the earth or natural disaster claim lives?

Some Christian preachers are claiming that the final blood moon of the ongoing tetrad, which fall on 28 September (27 September in some places), will witness the "end of the world". According to the apocalypse prophecy, the moon will appear reddish and disaster will hit humanity before the second coming of Jesus Christ.

Besides bringing in Biblical referrals, they claimed that the current tetrad is unique and in sync with the apocalypse prophecy. They hinted the blood moons coinciding with Jewish festivals with the first one clashing with Jewish holy day Passover, the second fell on the Feast of the Tabernacle, third fell on the Passover again, and the final blood moon on 28 September falls on the Feast of the Tabernacle.

Christian preachers and authors -- John Hagee, Julie Rowe and Mark Blitz -- have been openly talking about a possible disaster on 28 September. In the meantime, they have been accused of promoting their respective books by creating false alarm. Meanwhile, there are some others who think that a huge asteroid will hit the earth on the blood moon day, but there is not an iota of truth in the claim.

Will the world end on 28 September?

National Aeronautics and Space Administration (NASA) has rubbished the "end of the world" claims made by conspiracy theorists that an asteroid will hit somewhere near Puerto Rico between 15 and 28 September.

"There is no scientific basis -- not one shred of evidence -- that an asteroid or any other celestial object will impact Earth on those dates," Paul Chodas, manager of NASA's Near-Earth Object office at the Jet Propulsion Laboratory in Pasadena, said in a statement obtained by CBS News.

"If there were any object large enough to do that type of destruction in September, we would have seen something of it by now," said Chodas, adding, "In fact, not a single one of the known objects has any credible chance of hitting our planet over the next century."

Claims made by Christian preachers also don't make sense for the simple reason that blood moon is just an astronomical event due to coincidence of super moon and a total lunar eclipse. Tetrad has also happened several times in the past and will happen again in the future.

According to NASA, convergence of three lunar events -- total lunar eclipse, full moon nearest the fall equinox, closest approach to Earth for the year -- is a rare celestial event witnessed only five times since 1900. It last happened in 1982 and is due to happen on 27/28 September (date defers based on location) this year. The next one will happen only in 2033.
