- Shapes of asteroids
Asteroid near Earth
The 400-meter-wide asteroid 2005 YU55 is currently flying near Earth at over 13 km (8 miles) a second. On Tuesday, November 8, 2011, at 6:28 p.m. EST (5:28 p.m. CST; 23:28 UTC), it will pass Earth, coming within 325,000 km (202,000 miles), closer than the Moon’s orbit.
While 2005YU55 will stay a safe distance away, it is part of a crew of near-Earth asteroids. There are from 500 to 1000 near Earth asteroids, which diameter is estimated to be over 1 km .
It is the closest pass by such a large object since 1976. A similar event will not happen again until 2028. The closest recorded small asteroid to Earth during last decades is FU 162. The asteroid was discovered as it reached its closest approach to Earth on March 31, 2004. It traveled within … 6500 km of Earth’s atmosphere!
