The asteroid will be nearly 7 million miles away from Earth and poses no danger to the planet.

While Santa and his team of reindeer could catch a great view on their travels the space rock will not be in their path. But just to be safe they’ll stay in close contact with the crew from NORAD in Colorado Springs.
