The Earth will be on a date when the large "Florence" asteroid passes safely near it on September 1, 2017. The asteroid will travel about 7 million kilometers from Earth.
The asteroid, the largest asteroid near the Earth since NASA began tracking asteroids close to our planet, provides an important opportunity for scientists to study the asteroid closely, and the asteroid is expected to be an excellent target for the radar observatory on Earth. The asteroid approach is closest to Earth ever since 1890, and no such passage will occur near our planet until 2500. According to the "agencies".
Florence is one of the largest near-Earth asteroids, with measurements from NASA's Spitzer and NEOWISE showing a diameter of about 4.4 kilometers.
NASA quoted Paul Chaudas, director of the Center for Near-Earth Object Studies (CNEOS) in the US Jet Propulsion Laboratory as saying: "Many of the known asteroids passed near Earth closer to what Florence would achieve, but they were smaller Size.
