It’s currently traveling through space at more than 112,000kph and is getting 1.3km closer to Earth every second.

Is Earth on a collision course with an asteroid?

What is the biggest threat to Earth from space?

The Earth is in danger not only from asteroid strikes but also from their icy equivalents, comets. They could wreak havoc if they were to collide with our world. These objects usually live far away beyond even Pluto but can be jolted from their usual orbits by passing stars or gigantic gas clouds.

How would NASA stop an asteroid?

The asteroid would eject a stream of material that would act as a rocket, diverting the asteroid away from a collision course with the Earth.
