A simple telescope to see the asteroid that 'touched' the Earth

That night, around 00.28 hours has been a unique astronomical event.

This is the Asteroid 2005 YU55, which has been seen with a simple backyard telescope by hand (about 15 inches in diameter), and even with good binoculars . It's been a bright spot more between the light coming from other stars much farther away.

At a speed of 28,000 kilometers per hour, the asteroid 2005 YU55, which measures 400 meters in diameter, almost 'has brushed' the Earth's atmosphere in astronomical terms. At the time of closest approach, found 320,000 kilometers away , to 0.85 lunar distances, ie, closer than the moon.

Those who have managed to capture their movement may have noticed, though slower than an airplane, but enough to capture how it moves in real time.

Discovered six years ago by Robert McMillan Spacewatch telescope at the Observatory of the University of Arizona, 2005 YU55 was found again in April 2010. In 1976 also came to Earth , even more than now, but then went unnoticed .
