Asteroids. Near Misses...
This is very exciting and a little freaky too.
How close is too close? Here is what NASA scientists have to say about the Asteroid 2005 YU55 that will fly very close to Earth -- slightly closer than our moon's orbit. And it all happens today November 8th.
From 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.
NASA detects, tracks and characterizes asteroids and comets passing close to Earth using both ground- and space-based telescopes. The Near-Earth Object Observations Program, commonly called "Spaceguard," discovers these objects, characterizes a subset of them, and plots their orbits to determine if any could be potentially hazardous to our planet.
