Asteroid close call for Earth

The above webpage refers to the asteroid that missed earth by only 48,000 miles which is much closer than the moon.

My question would be: Will this asteroid hit earth on its next orbit around the sun? or the next?

I also wrote the other night about the year 7120BC as the year a meteor hit in the Hudson Bay near Canada and forever changed the landscape by inundating most of the northern hemisphere under water except mountains. This is a likely date for Noah's ark, Atlantis sinking and even the red sea withdrawing for Moses because the ocean water effects in the southern hemisphere would have been less coming up the right side of Africa than say in England when it created a permanent separation between England and Europe through the English Channel at that time.

So, things like meteors and asteroids if they are large enough can and do hit earth from time to time. If they are smaller than a semi truck often they burn up in the atmosphere. However, the one that just missed us was the size of a ten story building. That size doesn't burn up and can do incredible damage whether it hits the ocean or on land. Either way. It is important to remember that the Gulf of Mexico was dug by a Asteroid or Meteor and extincted all the large dinosaurs on earth during that hit.
