Asteroid flyby today
 
http://www.jpl.nasa.gov/asteroidwatc...lease=2011-332

NASA scientists will be tracking asteroid 2005 YU55 with antennas of the agency's Deep Space Network at Goldstone, Calif., as the space rock safely flies past Earth slightly closer than the moon's orbit on Nov. 8. Scientists are treating the flyby of the 1,300-foot-wide (400-meter) asteroid as a science target of opportunity - allowing instruments on "spacecraft Earth" to scan it during the close pass.

the trajectory of asteroid 2005 yu55 is well understood. At the point of closest approach, it will be no closer than 201,700 miles (324,600 kilometers) or 0.85 the distance from the moon to earth.
don't panic!!!!

So we could be getting a new moon if the Earth manages to grab hold of this ;)

So will we see it from here (if it ever stops raining that is)?

This is what some refer to as a cosmic bullet graze.

Simple answer no due to the cloud cover:)

But if we get a break in the cloud.....what time does it pass?

Even if there's no cloud you need a six-inch telescope (minimum) to see it because it's a black as charcoal, according to Nasa.

Even with a cloud-break you won't see with the naked eye:

"Amateur astronomers who want to get a glimpse at YU55 will need a telescope with an aperture of 6 inches (15 centimeters) or larger."

Ok, cheers.

There's no point standing outside and getting cold then!!

Apophis will be the closest yet... but we have a few years to "prepare" and teach geostationary satelites to dodge a bit.

Has that been named after a Stargate SG1 storyline? :erm:
