DETROIT (WXYZ) - This morning we caught up with Jim Green, Director of NASA's Planetary Sciences Division. He says while it is a big day for space scientists, the two headline grabbing events are unrelated.
We also talked about how close the asteroid - half of the size of a football field - will come to Earth. And the answer is very close - passing between the Earth and weather & cell phone satellites.
While this will be a close miss, Green says there are other potentially hazardous asteroids that NASA is watching. But they won't pose a threat to Earth for hundreds of years, a blink of the eye compared to the age of the universe.
