Researchers say that if a big asteroid collides on Earth, then due to this there will be a lot of devastation in the earth and oxygen will also decrease. However, he also believes that no big asteroid will hit the Earth for about 100 years now.

Now why did scientists warn

Scientists told that in the year 2019, the 100 meter long asteroid had passed near the Earth. It passed over a distance of 43 thousand miles and was seen just 24 hours before it passed the Earth.

NASA is keeping an eye
