A planet of nearly our Earth size will pass safely by our planet on 1^st September at a distance of more than 7.0 million kilometers (4.4 million miles). The planet is called Florence and it has been considered the largest near-Earth planets coming closer since the NASA managed its detection and tracking program. The Near-Earth Object Wide-Field Infrared Survey Explorer (NEOWISE) and NASA missions have indicated that planet Florence is more than 4.4 kilometers in its size. The upcoming encounter might provide an opportunity to scientists to study closely the planet and find more about the Florence planet. NASA has indicated that the planet Florence is expected to be a perfect target for ground-based radar observations. It would provide a significant amount of help in measuring the real size of Florence planet.

It would also provide insights on surface details as small as at least 10 meters. The manager of Center for Near-Earth Object Studies (CNEOS) of NASA, Paul Chodas said that there are various known planets have passed closer to our Earth than Florence as it will be passed on 1^st September 2017. But, planet Florence has been considered the largest planet to pass by our planet Earth closer since the start of the program of NASA to detect and track Near-Earth planets. Point to be noted that planet Florence had appeared close to Earth in 1890. NASA also indicated that it will not come closer to our Earth again before 2500. The agency also said that the planet can be visible using small telescopes in the last couple days of August and in the beginning of September 2017.
