Asteroids are small rocky bodies that normally sit in the inner solar system and orbit the sun. Millions of them fly in space and their collisions – so-called impact events – have shaped many planets significantly. However, they have also played a devastating role in Earth history, and it is believed that one has extinguished the dinosaurs, Express.co.uk said that "the likelihood of an impact is 100 percent, you just do not know when".
The same view holds leading osmochemist Natalie Starkey, who revealed this could be even beaten tomorrow.
During a StarTalk podcast recently broadcast with Neil deGrasse Tyson, the popular science communicator said: I'm naturally interested in where we're from.
"We are not very long on this planet, most of us are 1
"I would like to find out why we are here and how we are not here and what we leave to our future offspring.
"We may have come here only for comets and asteroids, and in the future we might die of comets and asteroids.
"They could collide with us and, as you know, devastate all humanity. "
Dr. Starkey, who is also Public Engagement Officer at the Open University, has called for more people to show interest in space rocks.
She added, "I want to understand these objects for many reasons, because we are so I came here, but also to protect ourselves in the future.

Luckily, leading space agencies like NASA expect no major impact anytime soon.
The US Space Agency said, "Experts estimate that an object the size of Chelyabinsk exploded in 2013 – about 55 feet – takes place once or twice in the century.  "It is expected that the effects of larger objects, ranging from centuries to millennia, will be far less common.
can occur at any time. "
