A THREE MILE wide asteroid is set to graze past Earth on Sept. 1 – and NASA says it’s the largest to come this close since they began keeping track

Cheyenne Macdonald – August 18, 2017

A massive asteroid estimated to be 2.7 miles wide is set to make a ‘relatively close encounter’ with Earth on September 1.

Dubbed ‘Florence,’ the huge space rock will pass just 4.4 million miles from our planet – or, about 18 times the distance between Earth and the moon.

According to NASA, this is the closest an asteroid of this size has come since they first began tracking near-Earth objects, giving scientists an unprecedented opportunity to study it up close through ground-based radar observations.

While it may sound alarming, NASA says asteroid Florence will safely fly past Earth at a distance of about 4.4 million miles (7 million kilometers).
