Impact Earth
... The Earth has been hit by NEOs before (see Box 1). We know this because impact craters can be seen in a number of places. Among the most famous is Meteor Crater in Arizona. Over 1 km wide and hundreds of metres deep, it has been dated to 49 000 years ago. It is estimated that the cause of this crate ...
