More than 800 asteroids at risk of hitting Earth in next 100 years, ESA warns

The idea of a huge asteroid smashing into Earth may sound like the plot of a science-fiction blockbuster, but according to the European Space Agency (ESA) , it could soon become a reality.

ESA estimates that there are currently 878 asteroids in the ‘risk list’ for hitting Earth.

The space agency explained: “This ESA catalogue brings together all asteroids we know of that have a ‘non-zero’ chance of impacting Earth in the next 100 years – meaning that an impact, however unlikely, cannot be ruled out.”

Worryingly, an impact by even a small asteroid could cause ‘serious destruction’, according to ESA.

To reduce the risk of such an event, ESA has joined with several international partners to search for asteroids, and develop technology to deflect them.

Over the next few days, planetary deference experts will meet in three locations across Europe to coordinate these efforts.

The first meeting will take place on 11-13 September in Rome, where experts will discuss NASA’s plans to crash its DART spacecraft into the 160-metre asteroid, Diymos-B.
