 Raymond Newport, WSAU News. Scientists are saying not to worry about two giant asteroids that are hurtling towards Earth. The European Space Agency says an asteroid over a mile wide will be zipping by the Earth this afternoon at a relatively close 4 million miles away. It poses no threat, but they say it's the closest flyby on record of an asteroid that size. On Saturday, another one will zip past our planet as well.
