Today on Tuesday, November 8, an asteroid with a diameter of 400 meters will approach Earth’s atmosphere. Named Asteroid 2005 YU55, and deemed “potentially hazardous” by the Minor Planet Center in Cambridge, Ma. will fortunately miss Earth by 0.85 lunar distance, or approximately 335,000 kilometers (208,000 miles).
The approach will mark the closest a known object with this size, has ever gotten to a collision with Earth since 1976. This will as far as we know, continue to hold true until Asteroid 2001 WN5 gets within 0.6 lunar distance in 2028. The Asteroid visiting this evenings was discovered 6 years ago in 2005, and was later named Asteroid 2005 YU55 accordingly. Since this discovery was done rather late, there is still possibility that scientists may find other large floating rocks heading our way before the arrival of Asteroid 2001 WN5 in 2028.
