Here's a graphic of the orbits ... seems we are in the danger zone twice a year.

Overall the top ten countries most at risk of being hit by an asteroid are: China, Indonesia, India, Japan, the U.S, the Philippines, Italy, the U.K, Brazil and Nigeria. If you live in any of those countries, don't panic as scientists often make mistakes!
NASA says a 40-meter asteroid would strike the Earth with an impact comparable to a 3-megaton nuclear bomb. A 2-km asteroid striking Earth "would produce severe environmental damage on a global scale," the space agency estimates, but an impact of that magnitude isn't likely to occur more than twice per million years.
So I think we will be ok!
