Asteroids are small rocky bodies in the inner solar system orbiting the sun. Millions of them fly around space, and their collisions, known as impact events, have played a significant role in the formation of many planets. NASA continually scans the cosmos and classifies any Earth-based objects (NEOs) as potentially hazardous objects (POPs) if they can pose a threat to life on Earth.
However, if from a distant space rock it still succeeds
Dr. Natalie Starky revealed one of the most far-fetched options during her new book, Catching Stardust.
Last year, she wrote, "If we have a very limited time, then we need an approach that can work for weeks or months.
" So a more radical method of avoiding impact with the Earth that can work on any ̵
There are some complications
" How about you orystannya nuclear weapons? This may seem like total madness, but believe it or not, scientists are considering firing such a device into a space object to break it into tiny pieces, perhaps even reducing it to a cloud of gas and droplets of liquid.  "This may seem like a great solution, but there is a potentially big problem."
However, Dr. Starky warned that saving humanity might not be easy.
She explained, "The shrapnel received from such an explosion as if it were very radioactive, so probably this is not something we would want to rain on the planet.
" It would almost certainly be if we undermined the object in the shortest time as it was heading to us.  JUST: Antarctica Breakthrough: Bizarre 250 Million Opening Exposes Shock of the Past
"If th Object was the one who often traversed Earth, moving ever closer to the impact of each orbit, it could have been blown up during a pre-emptive strike during one of her previous visits close to Earth before it was supposed to lead to complete destruction, "19359003]" Thus, any radioactive fallout k of destruction does not affect life on Earth.
"It may seem like a relief that whatever happens, there is a strategy."
Despite this, Dr. Starky raised a weighty point in view of the policy behind the firing of nuclear weapons in space.
She explained in detail: "There are some further complications.

There are millions of asteroids in space
"First, under the Space Treaty, nuclear weapons are prohibited from use in space. " as a major threat to Earth – an exception can be made to save us from future doom.
"Secondly, a modern nuclear warhead is unlikely to withstand the impact energy associated with this course of action.
" Instead, it will most likely need to explode close to space space. ; the object of having a nuclear explosion transfer it to another course, otherwise known as a nuclear explosion. "
Asteroid 101955 Bennu, officially known as 1999 RQ36, is a potential hazardous object listed in the risk table. the second highest overall rating on the technical impact hazard scale in Palermo.
They have already warned the space agency that it could be devastating if they did not act.
According to a study by scientist Maria Eugenia Sansaturio, the asteroid of 1999 could strike the Earth.
Dr. Sansaturio reported in the Solar System magazine Icarus warned that there was a high chance of an asteroid hit.
She told the Universe today in 2010: "The overall probability of an asteroid 1999 RQ36 impact can be estimated at 0.00092, about one-time one thousand chances, but most surprisingly, that more than half of this chance (0.00054) corresponds to 2182. "
However NASA has a less destructive move for Benn.
Four Threatening Asteroids
Space Currently, the agency is carrying out a mission with its space ship, REIS, OSIRIS learn more about rock.  The spacecraft spent two years chasing Benna before orbiting it for two more years and taking samples.
Then, in 2023, he will explode to Earth to allow scientists from all over the world to study him.
The mission team is particularly interested in exploring the role that asteroids like Benn – dark, primitive, and apparently carbon-rich – could play in creating life on Earth.
It will also help scientists clarify the chances of a strike on Earth. .
