Florence, a huge near-Earth asteroid, will pass safely by Earth on September 1, 2017, at a distance of about 4.4 million miles (about 18 Earth-Moon distances). It is amongst the biggest near-Earth asteroids ever recorded. To be more precise, measurements from NASA’s Spitzer Space Telescope and NEOWISE mission indicate it is about 2.7 miles in size.
