NASA has listed an asteroid bigger than the Great Pyramid of Giza for a “close approach” with Earth.
The space agency said the 2016 NF23 is hurtling rapidly at a speed of around 20,000mph. At that speed, it is around 15 times faster than the 1,354mph the retired Concorde traveled at.
The 2016 NF23 also measures up to a jaw-dropping 160metres. At that size, it is bigger than the Great Pyramid of Giza in Egypt which measures 139m.
It is listed on NASA’s Earth Close Approaches page, despite whizzing by at a distance of 3million miles away. But in space terms, it is considered close enough that it will pay attention to it.
At 160m, it is considered a “Potentially Hazardous Asteroid” because it is above 140m. It comes after a bus-sized asteroid zoomed past Earth earlier this month in the closest approach of the year.
But despite that, NASA still missed the 15-meter space rock that flew past at 20,636 miles. The space agency didn’t find the rock until the day after.
Amateur astronomer and high school physics teacher Tony Dunn explained on Twitter the asteroid was “undiscoverable prior to closest approach because it came from the direction of the Sun”.
Earlier this week terrifying footage also captured a fireball “40 times bigger than the Moon” shooting over the US.
