NASA is continuously attentive on the huge asteroids which are reaching the Earth day by day. Asteroid Watch Widget, the NASA website shows the next five comets and asteroids which are expected to pass by in the next few days.
One among these expected asteroids is about 1,100 feet wide (335 meters) which is nearly close to the size of the Wilshire Grand Center skyscraper in Los Angeles or a football stadium. And also it’s larger than the New York’s Empire State Building.
This asteroid is named as 2002 NN4 and NASA expects it to reach the Earth by Saturday, the 6th June. As per the reports of Tech Times, this particular rock is considered as an Aten-class Asteroid, but is also categorized by the space agency as a and Potentially Hazardous Asteroid (PHA) and as a Near-Earth Asteroid (NEA).
However, according to the scientists we needn’t be frightened as the threat for collision is too remote. The closest reach is expected to be a distance of 3,160,000 miles (over 5 million km.) away from home base.
It’s true that this asteroid is quite smaller than the ones which passed the Earth in past years. But, this is the largest one shooting across the milky way when compared with the other 4. The other three which are expected to shoot across are in the size of a house. Apart from that, the closest asteroid is expected to fly within 1,830,000 miles from Earth.
潜在的に危険な #小惑星 (PHA)アテン型の(163348)=2002 NN4が2020年6月6日に地心から約511万km(月迄の距離の13倍)まで近づきます. この天体は2002年7月9日に米国,ニューメキシコのLincoln Observatory ETSで発見されたもので推定直径は250-570mです. https://t.co/77MveSCLKdhttps://t.co/f3LygyjTdM pic.twitter.com/ruqdZxJuss

According to the researchers the asteroid’s orbit around the sun is completed every 0.82 years, or 300 days.
As per the scientists, numerous “close approaches” of the asteroid to the Earth are being predicted in the future. Only 30 close approaches are forecast at the moment and the return journey of 2002 NN4 will occur to our neighborhood in nine years, on 29th of June. If you are interested in waving this distant traveler, coming Saturday is the only ideal chance for a certain time.
According to the reports of Space.com, small asteroids pass our planet on a monthly basis. As per NASA Planetary Defense Officer Lindley Johnson’s statement. On April 28, 2020 HS7 is one example for such a small asteroid, which passes safely near the Earth many times each month.
“It poses no threat to our planet, and even if it were on a collision path with Earth it is small enough that it would be disintegrated by our Earth’s atmosphere,” the planetary defense official stated.
But 2020 HS7 has been able to come startlingly close to the planet, passing a journey of 26,550 miles (42,735 km) within the center of the earth and reaching only 750 miles (1,200 km) from the closest satellite in geostationary orbit, which is considered as the more distant satellite rings surrounding the planet Earth. The space rock was able to pass the satellite in a route below the satellite leaving it unscathed.
The flybys can be identified as a good display in action of our planetary defense apparatus. The authorities of space such as NASA and the Agency of European Space have identified these asteroids in our galactic “neighborhood” starting with the largest, along with their orbital trajectory. As the scientists are able to compile more data on these asteroids, their plotting of orbits and calculating the probability become more accurate.
