Natalie Starkey is a cosmochemist who cares about protecting Earth for future generations and is the author of the 2018 book Catching Stardust. In the text, Dr. Starky discusses how asteroids – the millions of small rocky bodies that lurk in the inner solar system – can end one day life on Earth. NASA is constantly scanning the Universe and categorizing all near-Earth objects (NOEs) as potentially dangerous objects (PHOs) if they could pose a threat.
However, Dr. Starky worries that history can repeat itself, igniting a cosmic winter on Earth that can kill humans in a few years.
She revealed that one of the most famous asteroid strikes is almost twice the size of Barj Khalifa, which is 800 meters away.
Dr Starkey wrote last year: 'As we have seen, the impact of the dinosaur killing was probably produced by a nine-mile (1
"Until it was able to destroy the entire planet, it certainly wasn't news about dinosaur foods or half the species that were there at the time.
"In fact, such an impact these days would ultimately kill all people, if not initially, after a few years.  "Such a collision can easily cause a long-lasting global cat astrophic effects on the planet's biosphere, caused by the onset of an impactful winter.
Dr. Starky explains how these conditions will affect people.
She added: "Here the sun's rays are blocked by the surrounding dust and debris fired by the collision.
"Under these conditions, any life that has escaped the direct effects of the impact will struggle to find enough food and resources to survive long after.

"Actually, the initial estimates suggest it may have collided with Earth, but after some careful observations, fortunately, they have developed this will go about 2.5 times farther from the distance from Earth to the moon, about 580,000 miles. ”
The asteroid 101955 Bennu, officially known as 1999 RQ36, is the PHO included in the Centre Risk Chart, with the second highest 1st Cumulative Impact Scale in Palermo.
Investigators are already warning the space agency that it could be detrimental if they didn't take action.
According to a study by scientist Maria Eugene Sansaturio, the 1999 asteroid could affect the Earth.  Dr. Sansaturio warned in a report on the Icarus Solar System magazine that there was a good chance of an asteroid being hit.
She told the Universe today in 2010: "The total probability of an asteroid 1999 RQ36 impact can be estimated to be 0.00092, approximately a thousand chance, but most surprising is that over half that chance (0.00054) corresponds to 2182. "
However, NASA has a less destructive move for Bennu.
The space agency is currently on a mission with its OSIRIS-REx spacecraft to find out more about the rock.
The spacecraft spent two years chasing Ben before orbiting him for another. two years and sampling.  Then, in 2023, it will explode back to Earth to allow scientists from all over the world to study it. The mission team is particularly interested in learning the role that asteroids like Bennu – dark, primitive, and seemingly carbon-rich – may have played in the creation of life on Earth.
It will also help scientists refine the chances of a blow to Earth.
