Washington: A 800-million-pound early warning system to find asteroids that are on a potential collision course with the Earth is set to be launched next month by European Space Agency.
The Gaia space telescope is going to track thousands of asteroids that are placed between Earth and the Sun that earlier used to blind telescopes.
The probe is going to be placed 145km from the Earth and is fitted out with the most high-powered video camera that has ever been built.
The probe has been designed to detect the type of meteors that blast which shook the Russian town of Chelyabinsk in February which left 1,600 people injured.
In its 5-year-mission Gaia will also map the stars with unprecedented precision, which will give astronomers the accurate distance between the stars in interstellar space.
