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!!!!

Re: Asteroid flyby today
So we could be getting a new moon if the Earth manages to grab hold of this

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

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."

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

Re: Asteroid flyby today
Has that been named after a Stargate SG1 storyline?
