So... did you catch that?

(You might need to watch it again—this time with speakers ON. You still won't see anything, but man, those sweet, sweet sounds.)

As reported, asteroid 2011 MD—which is about the size of a bus—came within 7,500 miles of the earth's southern hemisphere earlier today. From National Geographic:

About one asteroid around the same size as 2011 MD comes as close to Earth every five to ten years, and one strikes Earth roughly once every 50 years.

"This was not an extraordinary event in the world of close asteroid approaches," [MIT planetary scientist Ben] Weiss said.
