It will be on September 1, a NEO (Near-Earth Object), that is, a large object will pass close to Earth.
This passage, which will be safe, will occur about 18 times the distance from Earth to the Moon. According to NASA, this asteroid will pass a distance of 7 million kilometers and, due to its dimensions, Florence, named after this great Asteroid, is among the largest asteroids that have crossed paths with the planet Earth and is many kilometers in diameter.
All measurements of the Spitzer Space Telescope mission and NASA’s Near-Earth Object Wide-Field Infrared Survey (NEOWISE) mission indicate that this object has a diameter of about 4.4 kilometers.
The possible doubts that arise about the passage of an asteroid of this dimension so close to the Earth, are quickly undone and is perceived its impact, in the words of Areg Mikayelyan, director of Byurakan Observatory.
“The asteroid poses no threat to Earth. It will only leave a gravitational effect”.
Mikayelyan also added that NASA maintains a constant monitoring program on asteroids (15,000 asteroids recorded in its database) and assesses possible threats long before their passage.
This passage, according to the astronomer and according to the calculations, will take 12 days and will not rush towards another object to divert its orbit. Thus, Florence does not pose a threat to our planet, although it is considered to be passing too close to Earth. The gravitational effect it will leave will not be visible on our planet.
To better understand the gravitational effect, one can give as an example the gravitational attraction of the Moon that causes the tides to change on Earth.
However, since the asteroid is much smaller than the Moon, it will leave only an insignificant effect.The asteroid Florence was discovered by Schelte Bus at the Siding Spring Observatory in Australia in March 1981. Her name was given to Florence Nightingale, the founder of modern nursing.
This 2017 meeting is the closest to this asteroid since the year 1890 and also the closest. Until it passes through these sides, we will be in 2500. It will be visible to small telescopes for some nights as it moves through the constellations in which it moves. The constellations of Piscis Austrinus (Southern Fish), Capricornus, Aquarius and Delphinus.
