The space rock, dubbed 2006 VV2, came within 2.1million miles of hitting us which is a near miss in space terms, even though that's about nine times farther away than the moon.
The asteroid was flying past Earth on Friday night, at 11 p.m. (PDT), and on Saturday 7 a.m. GMT for Europe.
There was no danger of collision. And that's a really good thing. This space rock, named 2006 VV2, is more than a mile wide (about 2 kilometers), according to the Web site.

An asteroid is flying past Earth on Friday night at a minimum distance of about 2 million miles. That's about nine times farther away than the moon. There is no danger of collision. And that's a really good thing. This space rock, named 2006 VV2, is more than 2 kilometres wide. Image Hosted by ImageShack.us This image of asteroid 2006 VV2 was captured by astrophotographer Robert Long of the Astronomical Society of Las Cruces in New Mexico, using a CCD camera mounted on a 3-inch Orion ED80 refracting telescope.

2006 VV2 was discovered by LINEAR (MIT) on November 11, 2006.  It will approach within 0.023 AU  (8.8 lunar distances) on March 31 when it will be a very strong radar imaging target.  Its  physical properties are unknown, but its absolute magnitude of 16.7 suggests a diameter within  a factor of two of 1.5 km.  If past experience is a guide, then there is a ~1/6 chance that it is a binary system.
This is the closest approach predicted for an object this intrinsically bright until May 2036,  when (66391) 1999 KW4 will approach within 6.0 lunar distances.
Goldstone observations are scheduled on March 27, 30, and April 1-3.  
Arecibo observations are scheduled on March 31 and April 1.

Asteroid 2006 VV2 passes close to the Earth at the end of March and the early part of April.  At its closest, on March 31, it will be 0.0226 AU away (8.8 lunar distances). This will be the closest known approach by an object this intrinsically bright until May 2036, when binary asteroid (66391) 1999 KW4 (H=16.4) approaches within 6 lunar distances.
Observers should be able to see it through modest telescopes as it reaches 10th magnitude on March 31st and April 1st.
