An asteroid some 900 metres in diameter will have what in astronomical terms is deemed a 'close encounter' with earth today.
The nearest it will get to earth will be two million kilometres away, according to the US space agency, NASA.
It said there is no threat of a collision with our planet "now or for centuries to come".
