asteroids close to earth

The asteroid is about 1.1km in diameter, much longer than the Burj Khalifa in Dubai, which is over 0.8km tall.

Astronomers say the 2012 TC4 asteroid is likely to reach Earth on October 12 at a distance of 270,000km, Gizmodo reported on August 3.

Asteroid is a rock object, without air, that orbits the Sun and is too small to be called a planet.

An asteroid will glide over the Earth next Sunday. This event can be most clearly observed from New Zealand.

According to NASA, 1,400 asteroids are known to be potentially dangerous. Caltech's Jet Propulsion Laboratory office has been monitoring and publishing information about them
