Giant asteroids do not endanger the Earth

Asteroids about 500m in diameter are about to approach the Earth, but are not dangerous.

The US Aeronautics Agency (NASA) said that the 2004 Asteroid BL86 will fly over the Earth at a distance of 1.2 million km, nearly three times the distance from the Earth to the Moon.

Professional and amateur astronomers in the US, Europe and Africa can observe this phenomenon from 20h January 26 to 1am 27 January according to EST (8am-3pm on January 27, Hanoi time). ). A small telescope or binoculars are necessary for observing the 2004 BL86 asteroid.

"2004 BL86 does not threaten the Earth, but this is a relatively close approach from a large asteroid. Therefore, this is a special opportunity to be able to observe and study more," Reuters. quoted expert Don Yeomans said.

According to NASA, 2004 BL86 will be the largest asteroid to fly over Earth at this close range until the 1999 A10 asteroid appears.

Scientists plan to map the surface of 2004 BL86 using radar systems, as it flies through the Earth. Thereby, they can better define size, shape, rotation speed and other characteristics.
