An asteroid the size of a tour bus has zipped harmlessly past Earth.

The space rock flew 7,600 miles above the Earth's surface. It sailed high above the southern Atlantic Ocean at closest approach.

The asteroid was discovered last week by telescopes in New Mexico. It is between 15 feet and 60 feet wide. Scientists say asteroids this size sail past Earth every six years.

Earlier this year, a smaller came within 3,400 miles of Earth.

If the other asteroid they are talking about is 99942 Apophis then someone needs a brain scan cuz that rock is much larger than this one at ~1k ft diameter.

@ shootist and @SteWe

To clarify, Cave_Man was asking which asteroid they were referring to in the article when they stated "Earlier this year, a smaller space rock came within 3,400 miles of Earth."

Asteroid 2011 CQ1 passed by the earth at 3,400 miles of the earth on the 4th February 2011. This was about 1 or 2 metres in size.
