Don't worry asteroid 3122 Florence will safely pass at over 18 times the distance from the earth to the moon, but you could see it through a small scope or binoculars.

Large Asteroid Florence Will Fly by Earth on September 1

 

[ProjectBlueBook]

Florence is the largest asteroid to pass this close to our planet since the first near-Earth asteroid was discovered over a century ago.

3122 Florence is at least 2.7 miles (4.35 km) in diameter. The object that created Meteor Crater was a nickel-iron meteorite 50 meters (160 feet) across.

Not to worry.
The one that will hit is a ways off yet.
Not quite as big...IMHO

I think the one which would hit us won't be seen until it's too close to earth to warn many people...
