Big asteroid to sweep close September 1

Named for Florence Nightingale, asteroid 3122 Florence is the biggest near-Earth object to pass this close since this category of objects was discovered over a century ago! It might be visible in binoculars.
Asteroid 3122 Florence – named for the founder of modern nursing – on August 27 at 11:50 pm CDT as seen from central U.S. Illustration by Eddie Irizarry using Stellarium.
The next attraction coming up in our skies after the spectacular total solar eclipse of August 21 might be an asteroid big enough to be seen in small telescopes, and maybe even in binoculars, as a small, very slow-moving “star.” Asteroid 1981 ET3 – also known as 3122 Florence – is a huge space rock at least 2.7 miles (4.35 km) in diameter. According to Paul Chodas at the Center for Near Earth Object Studies:
FLORENCE IS THE LARGEST ASTEROID TO PASS THIS CLOSE TO OUR PLANET SINCE THE FIRST NEAR-EARTH ASTEROID WAS DISCOVERED OVER A CENTURY AGO.
Asteroid 3122 Florence will safely pass by our planet on September 1, 2017 at over 18 times the Earth-moon distance. The asteroid will not be visible to the unaided eye. It will, however, become visible in small amateur telescopes by late August, in the course of what will become the closest encounter to Earth by this asteroid since 1890.
It won’t come this close again until after the year 2500.
