Protecting the Earth from Killer Asteroids

Description:  Asteroids have the potential to cause catastrophic loss of life on our planet upon impact. In 2013 the Chelyabinsk meteor injured 1500 people when it exploded over Russia. If researchers could identify potential asteroids early enough they could change their orbit to eliminate the threat to Earth. This phenomenon could be used to explore the motion of orbiting objects in the solar system or to gain a better understanding of gravitational forces and fields.
