Professor Alan FitzSimons, of Queen’s University Belfast, told the media recently that it was only a matter of time before an asteroid hit Earth and destroyed humans. Humans are almost unable to withstand the effects of an asteroid impact, the professor warns, threatening to end life on Earth. If not protected, the planet could face a deadly catastrophe.
Astronomers are currently tracking nearly 2,000 earth-threatening asteroids, comets and other objects, and discover new and threatening asteroids every day.
Although Earth has not seen an asteroid that has been wiped out by a meteorite since it wiped out the dinosaurs 66 million years ago, an asteroid that can wipe out an entire city hits Earth at regular intervals.
As recently as 1908, a meteorite fell on Tunguska, burning 60 million trees over 2,150 square kilometers, a catastrophic scale.
But humans are also taking this threat seriously, and recently the European Space Agency has approved the Hera anti-asteroid mission, which will test whether a deflected orbit can save humanity from asteroids that are heading toward Earth, a real-life exercise against an asteroid impact on Earth.
