A NASA senior scientist called on world leaders to spend more money on planetary protection from asteroids, warning if they couldn't be too little too late. Although asteroids hit the scale of the one that struck Earth 65 million years ago, ending dinosaurs' reign, are extremely rare, they are still possible, an expert has warned. NASA's Planetary Defense Officer Lindley Johnson said the impact could bring an end to humanity.
Mr Johnson told journalist Brian Walsh about his new book, End Times: "In the Order of Things, People Should Be Worried, Near Earth Objects is not high on the list.
"But it has the potential to be the most devastating natural disaster known to man.
"All the money would be worth it if they prevented an event that could take
" It is definitely worth the governments spending a little of their treasure to find these things ahead of time because you can't do anything unless you find them. .
Even asteroids on a much smaller scale still have the potential to cause enormous damage to our planet.
Scientists often cite two relatively recent incidents where space rocks have not been discovered that prove the Earth is still vulgar .

Part of the reason NASA sent the OSIR space we gather more information about the space rock, which is 500 meters long.
NASA fears that an asteroid that has the potential to destroy a Earth state may strike our planet within the next 120 years, with the next one near 2135.
The mission will provide vital information on how to divert asteroids from our collision with Earth.
But NASA again states that while there is little chance of Earth being affected, "for millions of years, by all planets, Bennu is most likely to strike Venus. "
ESA has invested 21 million pounds in projects such as the Human Research Analog (Hera) mission, which will study the binary asteroid of Didymos, which is to fly past Earth in 2022.
Studies such as Hera will help ESA better understand how it can protect our planet from murderous asteroid strikes.
