Will the asteroid Bennu hit Earth?

NASA has just updated its predictions about the possibility of the asteroid Bennu slamming into Earth, even going so far as to pinpoint the exact date an impact is most probable: September 24, 2182. Bennu is expected to get within 125,000 miles of Earth — about half the distance to the moon.

What are the chances of Bennu hitting Earth?

To impact Earth on 24 September 2182 Bennu needs to pass through a keyhole roughly 5 km wide on 25 September 2135. The next two biggest risks occur in 2187 (1:14,000) and 2192 (1:26,000). There is a cumulative 1 in 1,800 chance of an Earth impact between 2178 and 2290.

What are the chances of an asteroid impact?

Dying from a global impact, which could be smaller than that of the famous Chicxulub asteroid that ended the reign of the dinosaurs about 66 million years ago? About 1 in 75,000. The chances of dying from a regional impact that doesn’t affect the entire Earth are actually smaller, about 1 in 600,000.

What would happen if Bennu hit the Earth?

If Bennu does impact Earth, it would create a crater between 10 to 20 times its size and cause an area of devastation that could reach 100 times the size of the crater, said Lindley Johnson, NASA’s planetary defense officer. The asteroid will make its next closest approach to Earth in 2135.

Which asteroid will hit Earth?

Bennu is classified as a potentially hazardous asteroid, or PHA. There is a small (1 in 2,700) chance that Bennu will hit Earth late in the 22nd century. If Bennu did hit Earth, it would release the energy equivalent of 1,450 megatons of TNT, creating an impact crater about 5 kilometers (about 3 miles) in diameter.

Will an asteroid ever hit Earth?

And no. Yes, an asteroid will hit Earth. In fact ten of them as big as refrigerators streak into the atmosphere every year. Most burn up on the way in, and about two-thirds of the rest (or chunks of them) fall harmlessly into the ocean (because the planet is about two-thirds ocean).
