Asteroid 2005 YU 55 will pass about 300-thousand kilometers from the
earth. The giant space rock is about 400 meters in diameter. The close
encounter will occur at 23:28 Greenwich Mean Time. Computer models
showing the asteroid’s path for the next 100 years show there is no
chance it will hit Earth during that time.
