Several space experts believe that earth will face an extinction event following a dreaded asteroid hits
It was on last July that NASA discovered a giant asteroid named 2019 ND7. This doomsday rock is more than 200 meters wide, and a potential hit on the planet could wipe out a city within a fraction of a second. Experts believe that a potential collision with 2019 ND7 will unleash energy equivalent to more than 1,000 atomic bombs exploded in Hiroshima during World War II, and millions of people will lose life instantly.
However, the chances of asteroid 2019 ND7 hitting the earth are very small. The United States space agency has calculated the risk at 1 in 310,000, which means there is a 99.99968 chance that this dangerous space rock will miss the earth. 2019 WG2 is a small asteroid when compared to 2019 ND7.
The asteroid is 35 meters wide, and NASA has calculated the risk at 1 in 4,000. As per NASA, 2019 ND7 may crash into the earth between 2097-2117 on 20 different occasions. On the other hand, 2019 WG2 may hit between 2098 and 2119 on 56 different occasions.
