A massive asteroid is set to skim the Earth on Saturday, December 16 - just over a week before Christmas.
With a diameter of about 3 miles, the asteroid is named 3200 Phaethon after the Greek demi-god who, according to legend, nearly set the Earth on fire.
Unlike its namesake, however, 3200 Phaethon is unlikely to destroy our planet.
It will pass within 6.5 million miles of the Earth, which is relatively close in space terms, but still around 27 times the distance of the moon.
"With a diameter of about 5 km, Phaethon is the third largest near-Earth asteroid classified as 'Potentially Hazardous'," NASA said in a statement .
Scientists at NASA's Jet Propulsion Laboratory are planning to use the opportunity to obtain a detailed 3D model of the asteroid, which has a particularly irregular shape.
