Florence is 2.7 miles wide, making it the largest asteroid ever tracked by NASA's Jet Propulsion Laboratory. "While many known asteroids have passed by closer to Earth than Florence will on Sept.1, all of those were estimated to be smaller," Paul Chodas, manager of NASA's Center for Near-Earth Object Studies at the agency's Jet Propulsion Laboratory in Pasadena, California, told al.com. "Florence is the largest asteroid to pass by our planet this close since the NASA program to detect and track near-Earth asteroids began." Asteroid Florence was discovered in 1981 by Schelte "Bobby" Bus at the Siding Spring Observatory in Australia.

What are the chances that their math is a bit off? That's pretty close.
COULD THIS ACTUALLY HIT EARTH?!?!?!?!??!?!
Boy I hope so, I haven't been this excited since mario bros 3 came out on NES.

So, how is it doomporn if it is passing at such a safe distance?
Florence, an asteroid that came within 4.4 million miles (7.0 million kilometers) of Earth last week, has two small moons, according to radar images obtained by NASA.
Radar images obtained between August 29 and September 1, when Florence came closest to Earth, reveal that the asteroid is about 2.8 miles (4.5 kilometers) in size, the US space agency said.
It said the two moons were probably between 300-1,000 feet (100-300 meters) across.
The inner moon takes approximately eight hours to revolve around Florence while the outer moon takes between 22 and 27 hours, NASA said.
