In what look for all the universe like a cCosmic April fools joke asteroid called 2012 EG5 passed the Earth at just 143, 000 miles which is about 100,000 miles closer than the Moon. While the 150 foot across asteroide was never in any danger of colliding with the Earth it was still close
It had been less than a week since two smaller asteroids had come even closer. On asteroid was about the size of a bus and passed within 96,000 miles of Earth. The other asteroid was the size of a car and passed just 36,000 miles away.
Even if one of these small rocks did hit the Earth they are too small to do any real damage unless they hit a populated area.
