NASA has identified a new asteroid that is expected to make an approach to earth so close in 2030, it has gotten the attention of the United Nations.

Asteroid 2011 AG5 is expected to make a “keyhole” pass by earth in 2023 before finally returning in 2030 where it will have a 1 in 625 chance of impacting the earth. Scientist warns those odds are likely to get worse as they track the asteroid better, saying the projected pass of about just 0.02 astronomical units from earth is about the most it will miss us by.

Were the rock to land on a city it could cause millions of deaths, although mankind would live through it.

The asteroid which wiped out the dinosaurs 65 million years ago was nine miles wide, compared to 460ft for the 2011 AG5.

At 460ft, if it were to hit New York or Los Angeles, it would wipe out the entire metro area population.

Much of the world’s attention on asteroids has been on the Apophis asteroid, which is the size of two and a half football fields and is predicted to pass close to Earth in 2036.

If the forecasts are true it will come within 18,300 miles of Earth’s surface and will be visible from most of Europe, Africa, and Asia.
