A GIANT death star is heading Earth’s way which could wipe out life on the planet, scientists have warned.
Once it is there in what is known as the Oort cloud, which is full of of asteroids, it could fling all of the space rocks our way, wiping out life on Earth.
Swinburn University astrophysicist Alan Duffy told Australia’s Herald Sun: “Objects hardly ever meet in space — the distances are so huge — but the gravitational influence of a star is enormous, even something a lightyear away can rattle the loosely held Oort Cloud objects.
“But there’s no doubt that nearby stars in the past have nudged Oort objects into falling towards the inner solar system.”
He wrote on his MPIA page: “I am interested in the history of the Earth and astronomical phenomena have clearly played a role in this.
The star will be about three light years from Earth, according to the study published in the journal Astronomy & Astrophysics, but experts say that it is unlikely to come for another 240,000 years.
The study reads: “The closest encounter appears to be Hip 85605, a K or M star, which has a 90 per cent probability of coming between 0.04 and 0.20 parsecs [8,000 AU] between 240,000 and 470,000 years from now (90 per cent Bayesian confidence interval).
“However, its astrometry may be incorrect, in which case the closest encounter found is the K7 dwarf GL 710, which has a 90 per cent probability of coming within 0.10-0.44 per cent in about 1.3 million years.”
