News Nation on Wednesday reported that a pair of deadly asteroids (space rocks) dubbed as 1998 FF14 and 2019 SW1 had zip past the Earth. Well, Earth is all set to have a close encounter with another pair of asteroids identified as 2019 QY3 and 2017 KP27. Yes, you read it right. If these two asteroids hit the Earth, massive casualties may occur. Notably, asteroids are small, rocky objects that orbit the Sun. Although asteroids orbit the Sun like planets, they are much smaller than planets. The celestial bodies can bring tsunamis, shock waves and flattening winds that could be catastrophic. The space rocks approach towards the Earth due to the gravitational forces that affect them. It is said that one day, all life on Earth will extinct and an asteroid could be the possible reason. Shocked to hear that? However, a car-sized asteroid slams into the Earth's atmosphere about once in a year. On the other hand, an asteroid large enough to threaten the existence of life on Earth arrives once in every few million years.
Coming back to asteroid 2019 QY3, the space rock is dangerously approaching the Earth at a staggering speed of more than 20,900mph. Relax, the space rock will not hit our planet and we are safe. During its closest approach, asteroid 2019 QY3 will be 0.01455 astronomical units (au) away from Earth. The asteroid will miss the Earth by a margin of 1.35 million miles (2.17 million km).
NASA estimates that the asteroid measures somewhere in the range of 137.8ft to 311.7ft (42m to 95m) in diameter.Another asteroid that will approach Earth today is identified as 2017 KP27. This asteroid is traveling at speed of about 10,500 miles per hour and is estimated to be about 135 feet long. Asteroid 2017 KP27 has 0 per cent chances of hitting our planet and it will zip past the Earth.
It is worth mentioning here that according to a report published by spacetelescope.org, there are more than 7 lakh asteroids that have been found in space.
