Asteroid Florence, a major asteroid close to the Earth, will pass safely at a distance of about 7.0 million kilometers or about 18 Earth-Moon distances on 1 September 2017). Florence is one of the closest asteroids of the Earth a few kilometers long; The measurements from NASA's Spitzer Space Telescope and NEOWISE mission show that it is about 4.4 miles in size.

Paul Chodas, director of NASA's Near Space Research Center (CNEOS), at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif. "Despite the fact that many known asteroids are closer to the Earth on January 1, it is estimated that all of them are smaller. Florance is the greatest asteroid in this closeness to our planet since the NASA program was launched to find and follow Earth planetary asteroids. "

This relatively close encounter allows scientists to study this asteroid closely. Florance is expected to be a perfect target for ground-based radar observations. NASA's Radar imaging is planned on the Goldstone Solar System Radar in California and the National Science Foundation's Arecibo Observatory in Puerto Rico. The resulting radar imagery will show Florence's actual size and surface details as small as 10 meters.

Asteroid Florence was discovered in March 1981 by the Schelte "Bobby" Bus in the Siding Spring Observatory in Australia. The founder of contemporary nursing is given in honor of Florence Nightingale (1820-1910). The match in 2017 will be the closest thing to this asteroid since 1890 and will remain the closest after 2500. Florance will shine forth in late August and early november, and Piscis will appear in small telescopes for several nights during the constellations of Austrinus, Capricornus, Aquarius and Delphinus.
