There are currently 878 asteroids at risk of hitting the Earth in the next 100 years, according to the European Space Agency.
The agency added that an impact by even a small asteroid could lead to 'serious devastation' and, to reduce the risks of a collision, the ESA and several other groups have joined together to search for asteroids.
They are also developing technology to deflect space rocks and will discuss potential tactics at several meetings across Europe over the next few days.
It comes as NASA warned of an asteroid bigger than the Empire State Building passing close by the Earth this week.

The space rock, called the 2000 QW7 will, skim past the planet at more than 14,000 miles per hour on Saturday.
Though it should only come within 3.3 million miles of the Earth, that is considered a 'close approach' by NASA.
The asteroid has an estimated diameter of anywhere from 951 to 2133 metres, meaning that it would be the second tallest building on Earth.
As per NASA policy, any fast-moving space object within 4.65 million miles of Earth is considered to be 'potentially hazardous'.
The ESA said: '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.'
