Talk about a close shave... Luckily even if it hit this one was relatively small.
A big one on the other hand...

Bus-size space rock could have made "decent-size crater" if aimed at us.

An asteroid the size of a school bus gave Earth an extremely close shave around 1:14 p.m. ET today.

The rogue object—dubbed asteroid 2011 MD—buzzed by at a distance of 7,500 miles (12,000 kilometers) from our planet's surface, or roughly 30 times closer than the moon.

Researchers with MIT's Lincoln Near Earth Asteroid Research (LINEAR) program discovered the asteroid on June 22 and pegged its size between 20 feet (6.3 meters) and 46 feet (14 meters) wide.

Astronomers clocked its top speed at around 63,000 miles (101,000 kilometers) an hour.

Although small by asteroid standards, 2011 MD was close enough for amateur astronomers to spot it with modest telescopes.
