An asteroid came super close to Earth but NASA wasn't worried
An asteroid passed 26,000 miles from Earth early Thursday morning, but NASA scientists weren't alarmed: They had been waiting for this space rock, named 2012 TC4, to cruise by for around five years.
The asteroid is estimated to be about 45 to 100 feet in diameter, so it never had the potential to catastrophically harm the Earth.
However, it still got pretty close in cosmic terms. A distance of 26,000 miles is about one-tenth the distance between Earth and the moon. There are also hundreds of satellites orbiting Earth at about this distance.
