Bennu – the diamond-shaped asteroid that scientists believe contains the early “seeds of life” of the solar system – still has a certain proportion of danger to Earth, according to NASA.

According to the AP, NASA’s new statement based on research led by Dr. Davide Farnocchia from the Center for Near-Earth Object Studies at NASA’s Jet Propulsion Laboratory says the odds of Bennu hitting Earth are high. more in the new calculation, but don’t worry about it too much either.

The study builds on many of the data that NASA’s Osiris-Rex spacecraft has recorded. This spacecraft has now approached Bennu for a mission to retrieve a sample directly from the asteroid to bring back to Earth, expected to arrive in 2023.

Before Osiris–Rex arrived, scientists believed that the odds of Bennu hitting Earth were 1/2,700 in the years until 2200. But now, new data suggests the odds should be 1/1750 until 2300, in which the most dangerous day is September 24, 2182.

According to CNN, NASA reassures that the odds are still low and you can still believe you are safe at least this century.

If Bennu were to crash into Earth, it wouldn’t be enough to cause a mass extinction comparable to the impact 66 million years ago that killed the dinosaurs, but could create a giant impact crater 100 times larger than the original. asteroid body.

However, NASA still has quite a few “Earth defense” plans, including a mission to use a “suicide” spacecraft to knock back the asteroid announced in November 2020. They believe that with the technological development of the next 100 years, it will be even easier to protect the Earth.
