An asteroid listed as “potentially hazardous” by NASA and estimated to be about the size of the Great Pyramid of Giza is hurtling toward Earth at 20,000 mph – but don’t cancel your end-of-August plans just yet.
The giant space rock, known as 2016 NF23, measures between 230ft and 525ft in diameter and is expected to make a “close approach” to Earth on August 29. NASA labelled the asteroid as an “Atens” body, meaning its orbit will come into the vicinity of our planet, and has put it on their “potentially hazardous asteroid” list.
