Asteroid as big as three buses heading our way

The asteroid is officially called 2020 SX3 and it’s heading towards earth.

The bad news is that this space rock is between 38 and 86 metres across, according to NASA – that’s about the size of three double-decker buses.

The good news is that it should swing past our home planet (Earth) with no chance of a direct hit.

It will be travelling at a mind-blowing 10.88 kilometers per second which is around 40,000 kilometres per hour.

NASA says although the asteroid will fly by at a distance of 1.7 million kilometres, it is close enough to be considered a near-Earth object (NEO).

“NEOs are comets and asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter the Earth’s neighbourhood.” NASA explains.

The asteroid will be closest to earth on October 8
