KEY POINTS

  • NASA detected almost 80 potential Earth Impacts from asteroid Bennu
  • A video explained what would happen to Earth if it gets hit by Bennu
  • Bennu would generate mega-tsunamis if it hits the ocean 

A video explained the possible violent aftermath of a major impact event on Earth caused by the asteroid Bennu. According to the video, the asteroid strike could generate towering tsunamis that would travel for several miles from the point of impact.

Asteroid Bennu is one of the most dangerous asteroids that NASA is currently monitoring. As indicated in the database maintained by NASA impact monitoring system Sentry, Bennu, also known as 1999 RQ36 could cause 78 potential impacts between 2175 and 2199.

Last month, the YouTube channel Destiny posted a video to discuss the nature of the asteroid and its possible effects on Earth following an impact event. As noted by the video’s narrator, the asteroid, which measures about 1,607 feet wide, would cause a significant level of destruction on Earth.

Although it won’t trigger extinction-level scenarios, the impact from the asteroid would wipe out large areas that are as big as cities or even states. It would create a crater that’s almost three miles wide and cover its surrounding area with debris shortly after impact. Aside from this, the massive asteroid strike might also trigger powerful earthquakes.

“At a distance of 3.1 miles away, the debris would arrive in just 32 seconds after the impact, everything in the area would be buried under 51.6 feet of the projectile,” the video’s narrator stated. “No fireball would be created, but the impact would trigger an earthquake with a 6.7 magnitude on the Richter Scale.”

As explained by the video, asteroid Bennu would certainly have a huge impact on Earth following a collision. But aside from the effects of a strike on land, the video also discussed what would happen if the asteroid hit the ocean instead.

According to Sentry’s data, Bennu could hit Earth with a velocity of over 13,000 miles per hour. Combined with the asteroid’s size and mass, these factors could guarantee that an ocean impact would create massive mega-tsunamis.

The narrator of the video noted that the asteroid strike could create tsunamis that are as tall as the Leaning Tower of Pisa in Italy. These would travel over 30 miles away from the impact zone and destroy everything in their paths.

“But let’s say Bennu impacted on the ocean, a tsunami wave 92, to 183-feet-tall would be generated and a distance 31 miles from the impact site, the wave would arrive in just eight minutes,” he said. “Life would be much safer 300 miles from the shore, but cities would still see dust and a major seismic event would follow.”
